Self-hosted WordPress search with relevant results, live AJAX search, WooCommerce support, multilingual indexing, and privacy-safe analytics.

== Description ==

**Softlinkster Semantic Search** is a powerful self-hosted search plugin for WordPress. Unlike cloud-based alternatives, all processing happens on your server — no external API calls, and no data leaving your site.

= Core Features =

* **BM25 Ranking** — Industry-standard text relevance scoring with TF-IDF weighting.
* **Live AJAX Search** — Instant search dropdown with thumbnails, prices, keyboard navigation, and accessibility.
* **Faceted Filtering** — Filter results by category, tag, post type, price range, stock status, and product attributes.
* **WooCommerce Integration** — Search products by SKU, attributes, variations; display prices and ratings in results.
* **Multilingual Support** — 10 language processors (English, Spanish, French, German, Arabic, CJK, and more).
* **Search Analytics** — Top queries, zero-result queries, CTR, click tracking, and CSV export.
* **Did You Mean** — Automatic spell correction with clickable suggestions.
* **Zero-Result Fallback** — Show popular content, recent posts, and trending queries when no results match.
* **Rich Result Cards** — Thumbnails, excerpts, prices, star ratings, and post type badges.
* **Privacy-First** — GDPR-compliant with anonymized session tracking, data export, and erasure.
* **WP-CLI Commands** — Index, reindex, compute IDF stats, export analytics, and diagnose.
* **Theme-Aware Search UI** — Search results, zero-result screens, and live search styling adapt to the active theme for readable output.
* **Classic Widget Support** — Add the search form to widget areas in traditional WordPress themes.

== Frequently Asked Questions ==

= Does it work without WooCommerce? =
Yes. It degrades gracefully to post/page search.

= Does it support Polylang and WPML? =
Yes, with graceful fallback when unavailable.

= How does the live search work? =
It uses the REST API with debounced AJAX requests. No page reload needed. Results appear in a dropdown with thumbnails, prices, and keyboard navigation.

= Is it GDPR compliant? =
Yes. Search analytics use anonymized session hashes. The plugin registers WordPress data exporters and erasers for privacy compliance.

= Does it work with block themes and classic themes? =
Yes. The plugin integrates with normal WordPress search flows on both block and classic themes. Classic themes can also use the included search widget in widget areas.
