Walkthrough

Adds pagination, filtering, and sorting to user search; makes search case-insensitive using ILIKE and fuzzy variants; adds parallel total-count retrieval; introduces public endpoints for search suggestions and popular searches; updates routing to expose these endpoints without auth.

Changes

Cohort / File(s)	Summary
User search controller updates platforms/pictique-api/src/controllers/UserController.ts	Expanded search to accept q, page, limit, verified, sort; input validation; parallel fetch of users and total count; returns pagination metadata and searchInfo. Added endpoints: getSearchSuggestions and getPopularSearches with validation and limits.
Public routes platforms/pictique-api/src/index.ts	Registered GET routes: /api/users/suggestions and /api/users/popular mapped to controller methods; public access (no authGuard).
User service search + helpers platforms/pictique-api/src/services/UserService.ts	searchUsers signature expanded (pagination, verified filter, sort). Implemented case-insensitive ILIKE across multiple fields and fuzzy query. Enforced isArchived=false, optional verified filter. Added getSearchUsersCount, getSearchSuggestions, getPopularSearches. Added Raw import and input guards.

Objective	Addressed	Explanation
Make search case-insensitive so it works properly ([#340])	✅

Assessment against linked issues: Out-of-scope changes

Code Change	Explanation
Add new public endpoint getSearchSuggestions and route (/platforms/pictique-api/src/controllers/UserController.ts, /platforms/pictique-api/src/index.ts)	Not related to making search case-insensitive; introduces a new feature.
Add new public endpoint getPopularSearches and route (/platforms/pictique-api/src/controllers/UserController.ts, /platforms/pictique-api/src/index.ts)	Not tied to the bug; adds unrelated discovery feature.
Introduce pagination, verified filter, and sorting in search (/platforms/pictique-api/src/controllers/UserController.ts, /platforms/pictique-api/src/services/UserService.ts)	Enhancements beyond the scope of fixing case sensitivity.
Add getSearchUsersCount helper and parallel count retrieval (/platforms/pictique-api/src/services/UserService.ts, /platforms/pictique-api/src/controllers/UserController.ts)	Performance/UX improvement, not necessary for the case-insensitive bug fix.

Poem

I burrow through queries, nibbling each byte,
Turned cases to cases that don’t fuss or fight.
With hops through pages and fuzzy delight,
I fetch you suggestions, stars shining bright.
Popular paths? I map them just right—
A pictique of profiles, tasty and light. 🥕🐇
