Fix name search missing short queries by martsokha · Pull Request #231 · nvisycom/server

martsokha · 2026-08-14T23:05:01Z

The bug

Searching files for "sa" did not find sample.txt.

Name search (files, pipelines, workspaces) filtered by the pg_trgm % similarity operator only (display_name.trgm_similar_to(term)). That operator is gated by a similarity threshold (~0.3) and needs roughly three characters of trigram overlap — a two-character query produces too few trigrams to clear the threshold, so short queries and pure prefixes matched nothing, even an obvious prefix like sa → sample.txt.

The fix

Make search a hybrid across all six search sites:

display_name.ilike(ilike_contains(term)).or(display_name.trgm_similar_to(term))

ILIKE %term% — predictable case-insensitive substring/prefix match that works for any query length: "sa" → sample.txt ✓, "amp" → sample.txt ✓.
OR trigram similarity — keeps typo tolerance: "smaple" still finds sample.

Both halves are served by the existing gin (display_name gin_trgm_ops) indexes, so no migration change is needed — that opclass accelerates ILIKE '%…%' as well as %.

`ilike_contains`

New query::search::ilike_contains wraps a term as a %term% pattern with its LIKE metacharacters (%, _, \) escaped in a single pass so they match literally. Notes:

The pattern is passed as a bound parameter (ilike($1)), never concatenated into SQL — so this guards against LIKE wildcard injection (a raw % matching every row), not SQL injection.
Escaping is one-pass (a \ emitted before each metacharacter), so there's no escape-ordering hazard that chained replace calls would have.
Unit-tested: contains-wrapping, metacharacter escaping (50%_off, a\b), and empty term.

Testing

cargo check, cargo clippy -D warnings, cargo doc, and the search unit tests all pass.

Summary by CodeRabbit

New Features
- Improved workspace, file, and pipeline search with case-insensitive partial matching.
- Added approximate matching to help find results despite minor spelling differences.
- Search terms now safely handle special characters.
Bug Fixes
- Applied consistent search behavior across counts, lists, pagination, and direct name searches.
- Preserved existing deleted-item filtering and pagination behavior.

Name search (files, pipelines, workspaces) filtered by pg_trgm % similarity only. That operator is threshold-gated and needs ~3 chars of trigram overlap, so a short query like "sa" produced too few trigrams to clear the threshold and matched nothing — searching "sa" never found "sample.txt". Make search a hybrid: a case-insensitive ILIKE substring match OR the trigram similarity match, across all six search sites. ILIKE gives predictable substring/prefix matching that works for any query length; the trigram half keeps typo tolerance. Both are served by the existing gin_trgm_ops index, so no migration change is needed. Add query::search::ilike_contains, which wraps a term as a %term% pattern with its LIKE metacharacters (% _ \) escaped in a single pass so they match literally. The pattern is a bound parameter (guards against wildcard injection, not SQL injection). Unit-tested for wrapping, escaping, and the empty term.

📝 Walkthrough

Walkthrough

The PostgreSQL query layer now provides escaped ILIKE contains patterns and combines them with trigram similarity for workspace, workspace file, and workspace pipeline name searches.

Changes

Hybrid name search

Layer / File(s)	Summary
Escaped ILIKE search helper `crates/nvisy-postgres/src/query/mod.rs`, `crates/nvisy-postgres/src/query/search.rs`	Registers the search module and adds `ilike_contains`, which escapes ILIKE metacharacters. Tests cover wildcards, escaping, and empty terms.
Workspace and file search filters `crates/nvisy-postgres/src/query/workspace.rs`, `crates/nvisy-postgres/src/query/workspace_file.rs`	Adds case-insensitive substring matching alongside trigram similarity for workspace names and workspace filenames. Count and item queries use the same filter.
Pipeline search filters `crates/nvisy-postgres/src/query/workspace_pipeline.rs`	Applies the combined filter to cursor counts, cursor results, and direct pipeline name searches. Documentation describes both matching modes.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to b89ce

The change broadens name search to support short and substring queries while preserving typo-tolerant matching; no actionable merge-blocking risk remains after normal checks and review.

offset_list_workspace_files takes a FileFilter but only honored extensions(), silently ignoring search_term(). No handler calls it today, so there was no live mismatch, but the method is part of the repository contract — apply the same hybrid ILIKE-or-trigram predicate so offset and cursor pagination search identically.
