Coveo Headless - groupBy functionality

[marbor3]

Hello!

I'm in the middle of quite some task - migrating from CoveoJSS for Sitecore into Headless, and I cannot find one important feature... Up to a point that searching through sources of ui-kit I cannot find it. I'm 95% sure it's a missing feature, so just wanted to make sure my thinking is correct, and ask if I can maybe help out.

I need to create a Tab component with a number of results inside each Tab.
I guess what I need is groupBy https://docs.coveo.com/en/1453/build-a-search-ui/group-by-operations
At least this functionality is used in the JSS version uses that - we listen for some events there, hook into the query builder, and add some stuff.

Some questions:

• is there groupBy functionality in Coveo Headless and should I read the manual more carefully?
• or this is not yet implemented, I should either wait patiently or open a PR here - that's my best guess and the reason I write here instead of asking ChatBot
• or I should use Facets for it, but then could a Facet accept an expression (as Tabs do)? Or maybe I should keep using HeadlessTab and just somehow return the count for each tab?

Thanks!
Best,
Marcin

Hey @marbor3 , sorry for the late answer!

Would https://docs.coveo.com/en/atomic/latest/reference/components/atomic-segmented-facet/ do the trick?

Hey!

Hmm, I was looking rather into headless as we have to heavily modify the styling.
But no worries I was able to solve it with preprocessRequest and modifying request there. Maybe not the most elegant way, but did the trick!
