What

Closes #21.

  • Parameterised search: getFuseOptions / createFuseSearch now accept { threshold?, keys? }. A bare threshold number still works, so v1.3-style calls (createFuseSearch(projects, 0.3)) keep working unchanged.
  • tagline in default keys: added at weight 1.5, the same tier as description — it's short, high-signal, description-like text, exactly what users search by. It was previously silently unsearchable.
  • Threshold aligned at 0.3 everywhere. Why 0.3: the docs already documented 0.3 as the default and useProjectSearch (the surface most consumers touch) already used it, so loosening createFuseSearch from 0.2 is the smaller behaviour change than making every hook consumer stricter. Single source: DEFAULT_FUSE_THRESHOLD in fuse.ts.
  • New pure searchProjects(projects, query, { threshold?, keys? }) — sibling to filterByStatus / sortProjects, usable outside React (server components, scripts). useProjectSearch now builds its memoised index via createFuseSearch and passes keys through.

Scope

No wider public-API redesign — FuseOptions shape unchanged, UseProjectSearchOptions just gained keys via FuseSearchOptions.

Tests

  • fuse.test.ts: 0.3 default, tagline key/weight, options-object + bare-number back-compat, custom-keys restriction, tagline search
  • searchProjects.test.ts (new): 11 tests covering passthrough on empty queries, per-field search, custom keys/threshold
  • useProjectSearch.test.ts: tagline default search + custom keys option

Verification

pnpm build && pnpm typecheck && pnpm lint && pnpm test — all green (1029 tests, vitepress docs build validates new page links).

Docs updated: fuse-search.md, new search-projects.md page, utilities index, use-project-search.md, customizing-search.md.

Note: no CHANGELOG entry — left to the release-manager flow.

Summary by CodeRabbit

  • New Features

    • Added fuzzy project searching with relevance-ranked results.
    • Searches now include project names, taglines, descriptions, and stack tags by default.
    • Added configurable search thresholds and weighted fields, with support for custom search keys.
    • Added a reusable searchProjects utility for querying project lists.
    • Existing numeric threshold configuration remains supported.
  • Documentation

    • Updated search guides, API references, examples, and usage recommendations for the new options and tagline searching.

…ault

- createFuseSearch/getFuseOptions accept { threshold, keys } options,
  with bare-number threshold kept working for v1.3 consumers
- add tagline to the default key set at the description weight tier (1.5)
- align default threshold at 0.3 everywhere (matches useProjectSearch
  and the documented default; single source in fuse.ts)
- add pure searchProjects(projects, query, opts) helper alongside
  filterByStatus/sortProjects; useProjectSearch now passes keys through
  and builds its index via createFuseSearch

Closes #21

Review Change Stack

Warning

Review limit reached

@ManningWorks, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 45 minutes

Limit details: You’ve used all 3 included reviews currently available.

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits within each organization.

For paid Pro and Pro+ reviews, CodeRabbit uses a developer's included PR review attempts over the past 7 days to set the current hourly allowance. At typical activity levels, the full plan allowance applies. Higher sustained activity can lower the allowance until earlier attempts leave the 7-day window.

Please refer docs for additional details.

📝 Walkthrough

Walkthrough

Changes

The search API now shares a 0.3 default threshold, searches tagline by default, accepts configurable weighted keys, preserves numeric-threshold compatibility, and adds the exported searchProjects helper. Hook behavior, tests, and documentation were updated.

Project search

Layer / File(s) Summary
Shared Fuse options and defaults
packages/core/src/lib/fuse.ts, packages/core/src/lib/index.ts, packages/core/src/lib/__tests__/fuse.test.ts
Fuse configuration now supports object options, weighted default keys including tagline, a shared 0.3 threshold, and numeric-threshold compatibility.
Pure project search helper
packages/core/src/lib/searchProjects.ts, packages/core/src/lib/__tests__/searchProjects.test.ts
searchProjects handles nullable or blank queries and returns relevance-ranked Fuse results for nonblank queries.
Hook integration and option forwarding
packages/core/src/lib/useProjectSearch.ts, packages/core/src/lib/__tests__/useProjectSearch.test.ts
useProjectSearch uses the shared Fuse factory and supports configurable keys while preserving empty-query behavior.
Search API documentation
packages/docs/src/api/utilities/*, packages/docs/src/guides/customizing-search.md
Documentation covers tagline matching, shared thresholds, configurable keys, searchProjects, and numeric compatibility.

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

Merge Risk: 🔵 Low · up to 9f6c1

The updated search behavior can omit newly added or changed projects when the project list changes, leaving results stale until another dependency changes. This is a bounded correctness risk that should have explicit owner follow-up before or after merge.

Greptile Summary

The PR adds configurable Fuse keys and thresholds, includes project taglines in default search, and introduces a reusable non-React search helper.

  • Preserves numeric-threshold backward compatibility while centralizing the default threshold.
  • Stabilizes equal-content custom key arrays to prevent unnecessary index rebuilding.
  • Expands tests and documentation for custom keys, thresholds, tagline search, and searchProjects.

Confidence Score: 5/5

The PR appears safe to merge.

No blocking failure remains.

Important Files Changed

Filename Overview
packages/core/src/lib/fuse.ts Adds shared search options, configurable keys, tagline defaults, and backward-compatible numeric thresholds.
packages/core/src/lib/searchProjects.ts Adds a pure fuzzy-search helper with empty-query passthrough and relevance-ranked results.
packages/core/src/lib/useProjectSearch.ts Passes configurable keys into Fuse and stabilizes equal-content inline key arrays, resolving the previously reported repeated index rebuild.
packages/core/src/lib/tests/useProjectSearch.test.ts Verifies custom search configuration and confirms that equivalent inline key arrays no longer rebuild the index.

intended field, avoiding overlapping name, tagline, and description matches.
Strengthen the threshold test to use a query whose results differ between strict

inequality rather than allowing equal counts; apply the same discriminating
terms and concrete expectations to the referenced test cases.

…uilt per render

useProjectSearch now pins keys to a content-compared identity via a ref,
so an inline keys array no longer busts the index useMemo on every
render. Adds index-rebuild counting tests via a spy around
createFuseSearch.

Addresses review on PR #31.
…d queries

searchProjects fixtures now use vocabulary unique to each field so
name/tagline/description assertions can only pass via the intended
field. Threshold tests in searchProjects, fuse and useProjectSearch
use single-deletion typos whose result sets differ between strict and
lenient thresholds, asserting exact sets plus strict inequality instead
of >=. Custom-keys test gains a positive control.

Addresses review feedback on PR #31.
