WP YetiSearch

Fast, typo-tolerant site search powered by SQLite FTS5. No external service required.

A WordPress integration of YetiSearch (yetidevworks/yetisearch): the index is an SQLite file on your own server, with relevance weighting, highlights, suggestions, facets (post type, taxonomies, price ranges, geo distance), an optional semantic layer, a public REST endpoint, an accessible typeahead, and a full WP-CLI surface. One index per language via Polylang or WPML.

Requirements

• WordPress 6.6+
• PHP 8.2+
• SQLite with pdo_sqlite and FTS5 (checked on the settings page with a self-test)

Install

1. Upload the release zip via Plugins → Add New → Upload, or copy the files to /wp-content/plugins/wp-yetisearch.
2. Activate the plugin.
3. Go to Settings → YetiSearch, enable the search engine, choose the content to index, and run the first index from the Maintenance tab (or wp yetisearch reindex).
4. Single-site only; multisite is not supported in 1.0.0.

Search from a theme

Nothing to change: the normal search results page is taken over server-side. Optional helpers:

• REST: GET /wp-json/yetisearch/v1/search?q=...&facets=1&filter[price][gte]=100
• Template tags and a typeahead script (see src/Search/template-tags.php).
• WP-CLI: wp yetisearch reindex, wp yetisearch check, and 7 more commands.

Full guide: USAGE.md (settings tour, theme/REST/CLI reference, multilingual, troubleshooting).

Development

composer install
composer test        # PHPUnit (unit + integration)
composer analyse     # PHPStan level 8
composer cs          # PHPCS with WordPress Coding Standards
composer verify      # all three gates in one command

End-to-end tests run against wp-env + Playwright (npx playwright test). Extra environment legs (WooCommerce, Polylang, WPML, CPT, load) run via bin/matrix-leg.ps1 -Leg woo|i18n|cpt|load|wpml|woopll. Release zips are built in Docker: bin/release-in-docker.ps1.
