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.

Kafka consumer throughput exceeded expectations at 12k events/sec. +- **Cross-team pairing.** Alex and David paired on the chart components, which reduced design-to-implementation feedback loops from days to hours. +- **CI/CD improvements.** Jordan's new GitHub Actions pipeline catches integration issues early. Zero broken-main incidents this sprint. +- **Documentation culture.** The team wrote ADRs for all major decisions, making onboarding a new contractor seamless. + +## What Didn't Go Well + +- **ClickHouse query tuning took longer than expected.** Some aggregation queries ran 10x slower than benchmarks due to suboptimal table engine choice. Cost us ~2 days. +- **Scope creep on the export feature.** The PDF export requirement grew from "basic table export" to "branded PDF with charts," adding unplanned work. +- **Flaky integration tests.** Three tests intermittently fail due to timing issues with the Kafka test container.

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. Reduce frame rate or dimensions if needed. +- **MP4:** Use H.264 for broad compatibility. Target 1-2 MB for short clips. +- **WebM:** Smaller than MP4 at same quality.
