  • changed filter params to accept repeated params
  • added data_source to filter params as an option from knowledge filter
    -safe guarded sentinel value * to not be taken as a literal
    -listFilesFilterParam no longer reduces array to one string; replaced with repeated-param serialisation
    -Fix: knowledge filter facet counts and option limits

Summary by CodeRabbit

  • New Features

    • Added support for selecting multiple connector types, document types, owners, and data sources when browsing or searching files.
    • Added data-source filtering for file searches and listings.
    • Filter options now display matching file counts.
  • Bug Fixes

    • Improved facet counts and filtering accuracy for exact-match searches.
    • Ensured counts are based on files rather than duplicate content segments.
    • Improved wildcard data-source handling and multi-value filter behavior.

Walkthrough

The PR adds repeatable file filters and data-source whitelists across the frontend and backend. It centralizes facet aggregation and normalization, counts unique files, resets pagination when filters change, and displays facet counts.

Changes

File filtering and facet counts

Layer / File(s) Summary
Facet aggregation counts
src/services/search_service.py, frontend/app/api/queries/useGetSearchAggregations.ts
Facet aggregations are centralized and normalized. Non-source facets use unique-file counts. Exact-match recomputation counts each facet value once per filename.
Multi-value file API and query filters
src/app/routes/public_v2.py, src/api/v2/files.py, src/services/file_service_v2.py, src/services/file_service.py, tests/unit/test_query_acl_filtering.py
File listing and search accept repeatable connector, MIME type, owner, and data_sources filters. Services emit term or terms clauses and omit wildcard-only filename filters. Tests cover single, multiple, wildcard, and combined filters.
Frontend filter and facet integration
frontend/app/api/queries/useListFiles.ts, frontend/app/knowledge/page.tsx, frontend/components/knowledge-filter-panel.tsx
Frontend query parameters use arrays and repeated query keys. Pagination resets when tracked filters change. The filter panel reads aggregation facets directly and displays numeric counts.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: ⚪ Minimal · up to 81eef

The filtering changes are merge-ready after normal checks and review; no actionable merge-blocking risk remains.

nit: .filter((v) => v !== "*") || undefined never yields undefined because empty arrays are truthy in JavaScript; the || undefined fallback is dead code

Only data_sources strips the "*" wildcard sentinel; connector_type, mimetype, and owner pass "*" through as a literal OpenSearch term filter that matches zero documents.

Functional review

Pagination doesn't reset on filter change

  • create a couple filters
  • select a filter and go to page 2
  • switch filters if the new filter is small you end up on an empty page

Plural vs Singular for filter selections (small cleanup would be nice to add to this PR)

The normalizer at line 88-89 deliberately strips doc_count from data_sources buckets. But when a token-like query triggers _apply_exact_match_file_filter, line 163 rebuilds all facets with doc_count. So the frontend will show "config.yaml (1)" for token queries but just "config.yaml" for prose queries — the count flickers on/off based on query shape.

On second though this isn't very important since the UI doesn't show these counts

the knowledge table already showed readable owner names, but the Owner dropdown in the filter panel was still displaying the raw owner ID. I updated the search aggregation response to keep the owner key for filtering while adding a label that can show owner_name / owner_email. The dropdown should now shows owner names with file counts
