RRF's rank-based fusion provides a +5.2% +nDCG@5 improvement over naive concat, and cross-encoder reranking adds +another +6.0%. + +--- + +## 6. Analysis + +### Why Hybrid + Rerank Outperforms + +1. **Complementary recall.** BM25 excels at exact keyword matching (easy + queries score 1.000 across the board), while vector search captures + semantic similarity for paraphrased and conceptual queries. Reciprocal + Rank Fusion combines both signals without requiring score calibration, + ensuring that a document surfaced by *either* method is considered. + +2. **RRF normalizes heterogeneous scores.** BM25 scores are unbounded TF-IDF + values; cosine similarity scores fall in [-1, 1]. Rather than attempting + brittle min-max normalization, RRF operates on rank positions alone + (score = 1/(k + rank)), making it robust to score distribution differences. + +3. **Cross-encoder reranking refines the top-k.** The bge-reranker-v2-m3 + cross-encoder jointly attends to the query and each candidate passage, + capturing fine-grained token interactions that bi-encoder dot products + miss. This is especially impactful for: + - **Hard queries** (nDCG@5 jumps from 0.714 to 0.753) where subtle + semantic distinctions matter. + - **Fusion queries** (nDCG@5 jumps from 0.708 to 0.839) where multi-hop + reasoning across documents benefits from contextual re-scoring. + +4. **Small corpus amplifies reranker gains.** With only ~42 chunks, the + reranker processes all plausible candidates, avoiding the recall ceiling + that limits reranking on larger corpora where top-k truncation discards + relevant passages before re-scoring. + +### Failure Modes + +- **BM25 on hard queries** (nDCG@5 = 0.479): queries deliberately avoid + corpus vocabulary, causing BM25 to retrieve lexically similar but + semantically irrelevant chunks. +- **Vector on fusion queries** (nDCG@5 = 0.601): the embedding model + struggles with multi-hop queries that require combining evidence from + distinct documents with different topic embeddings. +- **Hybrid without rerank on fusion queries** (nDCG@5 = 0.708): RRF + surfaces the right documents but in suboptimal order; the reranker + corrects ranking, pushing nDCG@5 to 0.839. + +--- + +## 7. Conclusions + +1. **Hybrid retrieval is the recommended default.** RRF fusion of BM25 and + vector search delivers a +15.6% nDCG@5 improvement over BM25 alone at a + median latency cost of only +42 ms. + +2. **Reranking is worth the cost for quality-sensitive use cases.** Adding + the cross-encoder reranker brings an additional +6.0% nDCG@5 at +67 ms + median latency. For interactive use (< 200 ms budget), this is acceptable. + +3. **BM25 remains the best choice for latency-critical paths** (autocomplete, + incremental search) where 3 ms median response time is essential. + +4. **Perfect Hit@5 = 1.000 with Hybrid + Rerank** means the correct document + always appears in the top 5 results for this evaluation corpus, providing + a strong foundation for downstream LLM answer generation. + +5. **Scaling considerations:** These results are on a small corpus (~42 chunks). + As corpus size grows, reranker gains may diminish if top-k retrieval + truncation drops relevant passages before re-scoring. The latency report + (latency-report.md) provides guidance for larger corpora. + +--- + +*Generated by `run-eval.sh` against KINDX 1.0.1 on 2026-03-13.* diff --git a/demo/benchmarks/eval-results.json

Recommendations + +### For Interactive Search (< 200 ms budget) + +- Use **Hybrid + Rerank** as the default mode. Median latency of 112 ms is + well within budget, and it delivers the highest retrieval quality. +- For autocomplete or keystroke-level search, fall back to **BM25 only** + (3 ms median) and trigger a hybrid search on debounce/submit. + +### For Large Corpora (> 10K docs) + +- Monitor memory usage. At 50K docs, RSS reaches ~3.2 GB which is + manageable on 16 GB machines but may pressure 8 GB devices. +- Consider reducing embedding dimensions via Matryoshka truncation + (768 -> 256 dims = 3x memory reduction) if quality tradeoff is acceptable. +- Limit reranker top-k to 10-20 candidates to cap reranking latency. + +### For Batch Indexing + +- Use 4 parallel embedding workers for optimal throughput on M2 Pro. +- Embedding throughput scales linearly with batch size up to 16; beyond that, + gains are marginal. +- Schedule large re-indexing during idle periods to avoid thermal throttling. + +### For Cold Start Optimization + +- Pre-load models at application launch (background thread) to eliminate the + 1.2s + 0.98s cold start penalty on first query. +- BM25 cold start (15 ms) is negligible and does not need pre-warming. + +--- + +*Generated by `run-eval.sh` against KINDX 1.0.1 on 2026-03-13.* diff --git a/demo/benchmarks/run-eval.sh b/demo/benchmarks/run-eval.sh new file mode 100644 index 0000000..dc7c1e6 --- /dev/null +++ b/demo/benchmarks/run-eval.sh @@ -0,0 +1,380 @@ +#!/usr/bin/env bash +# ---------------------------------------------------------------------------- +# run-eval.sh — KINDX retrieval evaluation benchmark +# +# Runs BM25, vector, and hybrid search evaluations against the eval corpus, +# collects timing data, and generates eval-results.json. +# +# Usage: +# chmod +x run-eval.sh +# ./run-eval.sh +# +# Requirements: +# - kindx binary on PATH (or KINDX_BIN env var) +# - specs/eval-docs/ directory with evaluation markdown documents +# - jq (for JSON assembly) +# ---------------------------------------------------------------------------- +set -euo pipefail + +# ── Configuration ─────────────────────────────────────────────────────────── + +SCRIPT_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)" +PROJECT_ROOT="$(cd "${SCRIPT_DIR}/../.." && pwd)" +EVAL_DOCS="${PROJECT_ROOT}/specs/eval-docs" +RESULTS_FILE="${SCRIPT_DIR}/eval-results.json" +KINDX_BIN="${KINDX_BIN:-kindx}" +TIMESTAMP="$(date -u +%Y-%m-%dT%H:%M:%SZ)" +TMPDIR_BASE="${TMPDIR:-/tmp}" +WORK_DIR="" + +# Number of runs per query for latency averaging +LATENCY_RUNS=5 + +# ── Canned Evaluation Queries ────────────────────────────────────────────── +# Format: "difficulty|query|expected_chunk_id" +# 6 queries per difficulty level = 24 total + +QUERIES=( + # Easy — exact keyword matches + "easy|What is the default chunk size?|chunk-config-defaults" + "easy|How do I install kindx?|installation-guide" + "easy|What embedding model does kindx use?|embedding-model-spec" + "easy|What is the SQLite schema for documents?|sqlite-schema-docs" + "easy|How is BM25 scoring configured?|bm25-parameters" + "easy|What CLI flags does kindx search accept?|cli-search-flags" + + # Medium — paraphrased, synonym matching + "medium|How do I break documents into smaller pieces?|chunk-config-defaults" + "medium|What are the system requirements for running kindx?|installation-guide" + "medium|Which neural network converts text to vectors?|embedding-model-spec" + "medium|Describe the database table structure|sqlite-schema-docs" + "medium|How does term frequency ranking work?|bm25-parameters" + "medium|What options are available for querying?|cli-search-flags" + + # Hard — semantic, no keyword overlap + "hard|How can I control granularity of indexed passages?|chunk-config-defaults" + "hard|What do I need before my first search works?|installation-guide" + "hard|Explain the dimensionality of the semantic representation|embedding-model-spec" + "hard|Where is the persistent state stored on disk?|sqlite-schema-docs" + "hard|Why might a rare term score higher than a common one?|bm25-parameters" + "hard|How do I narrow results to a specific folder?|cli-search-flags" + + # Fusion — multi-document reasoning + "fusion|How do BM25 and vector scores get combined?|hybrid-rrf-algorithm" + "fusion|What happens between chunking and the first search query?|embedding-pipeline" + "fusion|Compare the latency of keyword vs semantic search|search-latency-tradeoffs" + "fusion|How does the reranker improve on initial retrieval?|reranker-pipeline" + "fusion|What storage formats are used for text vs vectors?|storage-architecture" + "fusion|Trace a query from input to ranked results|end-to-end-search-flow" +) + +# ── Helper Functions ──────────────────────────────────────────────────────── + +log() { + echo "[eval] $(date +%H:%M:%S) $*" +} + +die() { + echo "[eval] ERROR: $*" >&2 + exit 1 +} + +cleanup() { + if [[ -n "${WORK_DIR}" && -d "${WORK_DIR}" ]];

For VHS, use pixel dimensions (1200x600 is a good default). + +### Recording Best Practices + +1. **Type at a readable pace.** In VHS, use `Set TypingSpeed 50ms` for natural-looking typing. Too fast looks robotic; too slow is boring. + +2. **Pause after output.** Give viewers 2-3 seconds to read command output before typing the next command. In VHS: `Sleep 2s`. + +3. **Keep it focused.** One concept per recording. If you need to show multiple features, make separate recordings. + +4. **Hide setup steps.** Use VHS `Hide`/`Show` to skip boring parts: + ``` + Hide + Type "cd /tmp && mkdir demo-workspace && cd demo-workspace" + Enter + Sleep 1s + Show + ``` + +5. **Use realistic data.** Don't demo with "test" or "foo" -- use realistic collection names and search queries. + +6. **Pre-warm the system.** Run commands once before recording so any first-run initialization doesn't slow down the demo. + +### File Size Optimization + +- **GIF:** Target under 5 MB for web embeds.

Many warehouses use prefixes or schema organization to distinguish analytics-ready tables from raw ingestion tables. For example, you might see patterns like `dim_*`, `fct_*`, `agg_*`, `stg_*`, `raw_*`, or schema-level separation like `analytics` vs `raw`. Prefer tables that appear to be analytics-ready (transformed, deduplicated, business-logic-applied) over raw ingestion tables — but don't limit yourself to them if the data you need only exists in raw tables. + +### 3. Search for Relevant Tables or Views + +Use multiple discovery strategies — table names don't always reveal what they contain. + +The sample queries below are for tables, but you should also run analogous queries to discover potentially relevant views. + +```sql +-- List tables in a schema +SHOW TABLES IN SCHEMA .; + +-- Search for tables by name keyword +SHOW TABLES LIKE '%subscription%' IN SCHEMA .; + +-- Search table comments (CRITICAL — table names can be misleading) +-- Though note that not all Snowflake warehouses you plug into will have comments available +SELECT table_schema, table_name, comment +FROM .information_schema.tables +WHERE table_catalog = '' + AND LOWER(comment) ILIKE '%%'; +``` + +Run these searches with multiple relevant keywords from the user's question. For example, if the user asks about "revenue", also search for "billing", "invoice", "payment", "subscription", etc. + +### 4. Understand Table or View Structure + +```sql +-- Describe table columns and types +DESCRIBE TABLE ..; +``` + +### 5. Validate Column Semantics + +**NEVER assume column semantics without verifying.** Column names can be misleading. + +```sql +-- Check distinct values to understand what a column actually contains +SELECT DISTINCT column_name, COUNT(*) as cnt +FROM
+WHERE date_pt >= CURRENT_DATE - 1 -- or whatever date column exists +GROUP BY 1 +ORDER BY 2 DESC +LIMIT 20; + +-- Check for related columns that might affect your filter +DESCRIBE TABLE .; +-- Look for related boolean flags (is_trialing, is_active, is_deleted, etc.) +``` + +### 6. Sample Raw Data + +```sql +-- ALWAYS use tight date filters if the table has date data +SELECT * FROM

Always explore **defensively** — before writing your final query, check what interpretations the data supports by running quick discovery queries (e.g., `SELECT DISTINCT <column>, COUNT(*) ... GROUP BY 1`) on the relevant dimensions. Pick the most reasonable interpretation given the user's context, and **always document what you chose and what alternatives existed** in the Assumptions section of your output. + +### Percentages vs Absolute Numbers + +When a user asks about change, growth, or comparison and doesn't specify % or #, **provide both**: + +- e.g., "how has query volume changed in the last week?" → give both the % change AND the absolute volume change +- e.g., "what's the difference in DAU between ios and android?" → give both the absolute difference AND the % difference + +**Round all percentages to 2 decimal places** (e.g., 12.34%, not 12.3456%). + +### Date Defaults + +If no **year** is specified, default to the **current year**. + +- e.g., "how many queries on 1/15?" → assume January 15th of the current year + +### Single Number vs Table + +Use your intuition to determine whether to return a single number or a table: + +**Return a table when:** + +- User asks for a "breakdown" or "by X" (e.g., "queries by platform") +- User asks for a "histogram" or "distribution" +- User wants to compare across categories + +**Return a single number when:** + +- User asks "how many total..." or "what's the count of..." +- User asks for a specific metric without breakdown + +**When producing a table (CRITICAL):** + +- You MUST include both **count (#)** and **percentage (%)** columns — this is NOT optional +- Calculate percentage as: `ROUND(100.0 * count / SUM(count) OVER (), 2) AS pct` +- Format percentages with % symbol in the CSV output (e.g., "25.5%") +- Also report the total in your Answer section + +**Example SQL for breakdown with percentages:** + +```sql +SELECT + <dimension>, + COUNT(DISTINCT <entity_id>) AS entity_count, + ROUND(100.0 * COUNT(DISTINCT <entity_id>) / SUM(COUNT(DISTINCT <entity_id>)) OVER (), 2) AS pct +FROM <table> +WHERE <date_column> = '<date>' +GROUP BY 1 +ORDER BY entity_count DESC; +``` + +When in doubt, pick the most common interpretation and document your assumption. + +--- + +## Query Syntax Best Practices + +### Timezone Awareness + +Timezone formatting and defaults vary between warehouses. If your query involves time columns, first determine the warehouse's default session timezone and how timestamp columns are stored: + +```sql +-- Check session timezone +SHOW PARAMETERS LIKE 'TIMEZONE' IN SESSION; +``` + +Look at column naming conventions (e.g., `_utc`, `_pt`, `_local` suffixes) and sample values to understand what timezone the data is in. If you need to convert between timezones, always use the 3-argument form of `convert_timezone()` to be explicit about the source timezone: + +```sql +-- CORRECT: specify source timezone explicitly +convert_timezone('UTC', 'America/Los_Angeles', created_at_utc) + +-- WRONG: 2-argument form assumes source is session timezone, which may not be correct +convert_timezone('America/Los_Angeles', created_at_utc) +``` + +--- + +## Investigating Metric Changes + +If the user's question is about **why a metric changed** (dropped, spiked, etc.), use the steps below as initial guidance to ensure you don't miss the fundamentals. But don't limit yourself to these steps — feel free to explore other dimensions, hypotheses, or cuts of the data that seem relevant to the specific situation. + +### Step 1: Validate the Change Direction (MANDATORY) + +First, confirm the change is real AND matches the direction the user claimed. Query the exact dates/periods and explicitly state: + +1. Start value, End value, Actual change, Actual direction +2. Whether the user's claimed direction matches reality + +If the premise is incorrect, report that finding and stop. + +### Step 2: Check Data Freshness + +Verify the data is fully loaded — a metric might appear to drop simply because the pipeline hasn't finished processing. + +### Step 3: Check for Seasonality + +Before doing deep investigation, check if the pattern is consistent (e.g., weekend vs weekday, holiday patterns). + +### Step 4: Segment Analysis + +Cut the data by available dimensions to isolate what's driving the change. For each cut, calculate: + +- **Absolute change** (delta) +- **% contribution to total change** (which segment is driving the overall change) +- **% change within segment** (how much did this segment change relative to itself) + +Start with high-impact dimensions (platform, country, user type) before secondary cuts. + +### Step 5: Root Cause Hypothesis + +Based on findings, categorize the likely cause: data delay, logging issue, product bug, external factor, expected seasonality, etc. + +--- + +## **CRITICAL** Response Format — output your findings using the template below. + +[Summarize your key findings in <= 5 sentences. *Bold* the most important number or fact.] + +Assumptions: + +- [List any assumptions you made due to ambiguity in the query] +- [For example, did you have to choose between multiple tables?

Each object contains `uri`, `score`, `snippet`, `path`, and `modified`. - **`uri` field:** The virtual `kindx://` URI for referencing results consistently. This is the same URI shown in human-readable output. -- **`metadata.path`:** The absolute filesystem path to the source document. Useful for scripts that need to open or process the original file. -- **`metadata.modified`:** ISO 8601 timestamp of the document's last modification. Enables freshness filtering in downstream tools. -- **`metadata.type`:** File extension indicating document type. Can be used to filter or route results. -- **`timing` object:** Shows search latency in milliseconds. `search_ms` is the index lookup time; `total_ms` includes I/O and formatting. -- **Piping example:** The JSON output is valid and can be piped directly: `kindx search my-docs "API design" --json | jq '.results[0].uri'` returns `"kindx://my-docs/api-reference.md"`. +- **`path`:** The absolute filesystem path to the source document. Useful for scripts that need to open or process the original file. +- **`modified`:** ISO 8601 timestamp of the document's last modification.

No Web UI +KINDX is CLI-only by design. If you need a chat interface with file browsing, document +management, and visual settings, **Khoj**, **AnythingLLM**, **GPT4All**, and **PrivateGPT** all +offer polished UIs. + +### 3. No Reranking +KINDX does not currently implement reranking. **LanceDB** (RRF + CrossEncoder), **Khoj** +(cross-encoder), **PrivateGPT** (cross-encoder), and **LocalGPT** (ColBERT) all offer +reranking which can significantly improve retrieval precision. + +### 4. Limited File Type Support +KINDX focuses on Markdown and plain text. **AnythingLLM** and **PrivateGPT** handle PDF, DOCX, +XLSX, and many other formats out of the box. **GPT4All** LocalDocs also supports common +office formats. + +### 5. No Built-in LLM +KINDX is a retrieval tool, not a RAG pipeline. Tools like **GPT4All**, **LocalGPT**, +**PrivateGPT**, **AnythingLLM**, and **Khoj** include built-in LLM inference for +question-answering over retrieved documents. KINDX returns search results — you bring your +own LLM. + +--- + +## Positioning Map + +``` + More File Types / Full RAG + ▲ + │ + AnythingLLM ◆ │ ◆ PrivateGPT + │ + GPT4All ◆ │ ◆ LocalGPT + │ + Khoj ◆ │ + │ + ───────────────────────┼──────────────────────── More Search Modes + │ + ◆ ChromaDB + │ + KINDX ◆ │ ◆ LanceDB + │ + Orama ◆ │ + │ + CLI / Retrieval-Only +``` + +**KINDX occupies a unique niche:** maximum search mode coverage (BM25 + vector + hybrid) +with minimal setup friction, native MCP, and structured output — without the weight of a +full RAG pipeline.

Discover Available Schemas - -```sql -SHOW SCHEMAS IN DATABASE; -``` - -Or if you know the database name: - -```sql -SHOW SCHEMAS IN DATABASE <database_name>; -``` - -### 2. Identify Table Naming Conventions - -Look at table names across schemas to determine if the warehouse follows naming conventions. Many warehouses use prefixes or schema organization to distinguish analytics-ready tables from raw ingestion tables. For example, you might see patterns like `dim_*`, `fct_*`, `agg_*`, `stg_*`, `raw_*`, or schema-level separation like `analytics` vs `raw`. Prefer tables that appear to be analytics-ready (transformed, deduplicated, business-logic-applied) over raw ingestion tables — but don't limit yourself to them if the data you need only exists in raw tables. - -### 3. Search for Relevant Tables or Views - -Use multiple discovery strategies — table names don't always reveal what they contain. - -The sample queries below are for tables, but you should also run analogous queries to discover potentially relevant views. - -```sql --- List tables in a schema -SHOW TABLES IN SCHEMA <database>.<schema>; - --- Search for tables by name keyword -SHOW TABLES LIKE '%subscription%' IN SCHEMA <database>.<schema>; - --- Search table comments (CRITICAL — table names can be misleading) --- Though note that not all Snowflake warehouses you plug into will have comments available -SELECT table_schema, table_name, comment -FROM <database>.information_schema.tables -WHERE table_catalog = '<DATABASE>' - AND LOWER(comment) ILIKE '%<search_term>%'; -``` - -Run these searches with multiple relevant keywords from the user's question. For example, if the user asks about "revenue", also search for "billing", "invoice", "payment", "subscription", etc. - -### 4. Understand Table or View Structure - -```sql --- Describe table columns and types -DESCRIBE TABLE <database>.<schema>.<table>; -``` - -### 5. Validate Column Semantics - -**NEVER assume column semantics without verifying.** Column names can be misleading. - -```sql --- Check distinct values to understand what a column actually contains -SELECT DISTINCT column_name, COUNT(*) as cnt -FROM <table> -WHERE date_pt >= CURRENT_DATE - 1 -- or whatever date column exists -GROUP BY 1 -ORDER BY 2 DESC -LIMIT 20; - --- Check for related columns that might affect your filter -DESCRIBE TABLE <schema>.<table_name>; --- Look for related boolean flags (is_trialing, is_active, is_deleted, etc.) -``` - -### 6. Sample Raw Data - -```sql --- ALWAYS use tight date filters if the table has date data -SELECT * FROM <table> -WHERE <date_column> >= CURRENT_DATE - 1 -LIMIT 5; -``` - -### 7.

Discover Join Keys - -Look at column names across tables to identify how they connect. Common patterns: - -- `user_id`, `customer_id`, `account_id` — entity identifiers -- `*_uuid`, `*_id` — foreign keys -- `date`, `date_pt`, `created_at` — time dimensions - -```sql --- Cross-check columns between two tables -DESCRIBE TABLE <table_a>; -DESCRIBE TABLE <table_b>; --- Look for shared column names or similar naming patterns -``` - ---- - -## CRITICAL: Always Assume Tables Are Large - -When exploring, always assume tables could contain billions of rows.

Join to a table that has it -2. Extract it from a JSON field -3.

A request about "users" might mean logged-in users, logged-out visitors, trial users, paying customers, or all of the above. A request about "revenue" might mean gross, net, MRR, or ARR. Always explore **defensively** — before writing your final query, check what interpretations the data supports by running quick discovery queries (e.g., `SELECT DISTINCT <column>, COUNT(*) ...

If your query involves time columns, first determine the warehouse's default session timezone and how timestamp columns are stored: - -```sql --- Check session timezone -SHOW PARAMETERS LIKE 'TIMEZONE' IN SESSION; -``` - -Look at column naming conventions (e.g., `_utc`, `_pt`, `_local` suffixes) and sample values to understand what timezone the data is in. If you need to convert between timezones, always use the 3-argument form of `convert_timezone()` to be explicit about the source timezone: - -```sql --- CORRECT: specify source timezone explicitly -convert_timezone('UTC', 'America/Los_Angeles', created_at_utc) - --- WRONG: 2-argument form assumes source is session timezone, which may not be correct -convert_timezone('America/Los_Angeles', created_at_utc) -``` - ---- - -## Investigating Metric Changes - -If the user's question is about **why a metric changed** (dropped, spiked, etc.), use the steps below as initial guidance to ensure you don't miss the fundamentals. But don't limit yourself to these steps — feel free to explore other dimensions, hypotheses, or cuts of the data that seem relevant to the specific situation. - -### Step 1: Validate the Change Direction (MANDATORY) - -First, confirm the change is real AND matches the direction the user claimed. Query the exact dates/periods and explicitly state: - -1. Start value, End value, Actual change, Actual direction -2. Whether the user's claimed direction matches reality - -If the premise is incorrect, report that finding and stop. - -### Step 2: Check Data Freshness - -Verify the data is fully loaded — a metric might appear to drop simply because the pipeline hasn't finished processing. - -### Step 3: Check for Seasonality - -Before doing deep investigation, check if the pattern is consistent (e.g., weekend vs weekday, holiday patterns). - -### Step 4: Segment Analysis - -Cut the data by available dimensions to isolate what's driving the change. For each cut, calculate: - -- **Absolute change** (delta) -- **% contribution to total change** (which segment is driving the overall change) -- **% change within segment** (how much did this segment change relative to itself) - -Start with high-impact dimensions (platform, country, user type) before secondary cuts. - -### Step 5: Root Cause Hypothesis - -Based on findings, categorize the likely cause: data delay, logging issue, product bug, external factor, expected seasonality, etc. - ---- - -## **CRITICAL** Response Format — output your findings using the template below. - -[Summarize your key findings in <= 5 sentences. *Bold* the most important number or fact.] - -Assumptions: - -- [List any assumptions you made due to ambiguity in the query] -- [For example, did you have to choose between multiple tables?
