Conversation
Keep typo recovery terminal and constant-bounded, enforce a three-second PostgreSQL deadline, cancel superseded browser work, and prevent per-key route transitions or translucent search repaints. Cover narrow one-to-three-character title paths, including the PostgreSQL parameter typing regression, and only label request-provider matches as outside the library after local search completes successfully.

navigation flow so clearing the prominent search immediately navigates to the

the old query navigation from running afterward. Preserve debounced navigation
for non-empty user input.
In `@web/src/hooks/queries/catalog.ts`:
- Around line 334-337: Update the query result assembly around page0Result and
remainingResults so isError and error include failures from visible remaining
pages, including omitted pages caused by search_timeout responses. Make refetch
retry the failed remaining page queries as well as page 0, while preserving
existing page-0 behavior when no remaining query has failed.

Problem
Related issue: #826
Closes #826
I use PostgreSQL FTS because I do not want a separate search daemon or a second copy of the catalogue. On a production-sized library, the existing PostgreSQL path was slow enough that normal title searches took several seconds, broad prefixes timed out, and each settled keypress triggered a full-page View Transition/repaint.
The measured catalogue had 15,826 media items, 141,104 aliases, 385,267 episodes, and 247,842 episode-catalog rows. The old main query averaged 4,659.2 ms and reached 26,187.7 ms max across 41
pg_stat_statementscalls.This PR keeps PostgreSQL as the only persistent search index. It does not add Meilisearch, Typesense, Bleve storage, a worker, or an application result cache.
Approach
PostgreSQL lookup path

This preserves PR #386's separate sparse fallback and pagination model. Fuzzy work remains terminal: page 0 only, fewer than five FTS hits, and at least one token of four characters.
pg_trgmindex scans, combined and permission-filtered before hydration. No alias scan is correlated to each media row.Request, memory, and CPU bounds
AbortSignal; cancellation does not emit a false 500.504 search_timeoutafter database work has stopped.retry: falseand a 30-second inactivegcTime; normal catalogue/request screens keep their existing cache policy.Web stability and result state
Not in your libraryis shown only after the local lookup completes successfully and is empty; loading, placeholder, and failed states use neutral discovery copy.MovieorSeries, andquota_exceededreadsRequest limit reached, so a same-title external movie is not confused with a local series or a search cap.Breaking Bad,Who Are You?,Up, and intermediate states such asthe m; without the guard, PostgreSQL rejected the generated statement withSQLSTATE 42P18.Benchmarks
All PostgreSQL figures below are from read-only
EXPLAIN (ANALYZE, BUFFERS, TIMING OFF)against the production-sized catalogue, limit 61, with a hard statement timeout. The final episode schema/index behavior was exercised with a transaction-local copy and rolled back during development.Old vs new PostgreSQL plans

The old column is the authenticated live resolver timing captured before this change. The new column is the final PostgreSQL plan time, so I am not presenting these as direct end-to-end ratios.

Local validation on the complete upstream diff:
Focused coverage includes title/overview gating, independent alias/canonical fuzzy arms, absence of correlated alias rescans, exact and leading short-token paths, data/count parameter typing, permission filters, duplicate prevention, pagination/totals, exact-title fuzzy suppression, typo ordering, cancellation, timeout response semantics, rapid typing, clear navigation, placeholder-page gating, interactive cache/retry options, request-provider state, and Movie/Series labels.
Final upstream GitHub Actions run
33238740125passed all three jobs on head0842865f: Docs hygiene (10s), Web (5m27s), and Go (7m17s). The Go job includes the full build, gofmt, vet, changed-linesgolangci-lint, generated-contract checks, andmake test-go; Web includes lint, formatting, production build,make test-web, and generated settings bindings.CodeRabbit reported four correctness edges and one inactive sort key. Each was reproduced against the current code and resolved in
1a9495f9: grouped timeout mapping, episode-overview refresh, clear/debounce ordering, failed later-page propagation/refetch, and removal of constanttitle_rank. All four review threads are resolved. Post-review reruns passed the affected Go packages, migration suite, all seven search Web files (86 tests), targeted ESLint with zero errors, and the production Web build; the final full CI run above also passed. CodeRabbit's final status is passing, with its additional review skipped by the service's rate limit after the lint-only0842865ffollow-up.Risks
NO TRANSACTION; invalid interrupted index remnants are removed on retry.AI Disclosure

The upstream port was then reviewed against PR feat(catalog): typo-tolerant Postgres search fallback (did-you-mean) #386, and the only merge conflict preserved both upstream's raised settings surface and this PR's opaque search surface. No unresolved finding remains.Checklist
