FacetWP Relevanssi integration

Description

The Relevanssi add-on connects the Relevanssi search engine to FacetWP facets, replacing WordPress native search with an error-tolerant index that supports typo tolerance, stemming, and searching in custom fields. After activation, the facets refine the results generated by Relevanssi, keeping ordering by relevance and highlighting searched terms on the front end of any file, shop page, or directory built with FacetWP.

Key Features

• Search and facet integration
  Makes FacetWP filter the results returned by the Relevanssi index instead of the standard WP query.
• Error-tolerant search
  Uses Relevanssi fuzzy matching and stemming even after applying category, taxonomy, or meta facets.
• Relevance-based sorting
  Keeps the ranking calculated by Relevanssi in the results filtered by the active facets.
• Custom field support
  Allows indexing custom fields and taxonomies and cross-referencing that indexing with facets configured in FacetWP.
• Compatibility with FacetWP templates
  Works in listing templates, files, and shop pages without requiring reconstruction of the existing layout.

Relevanssi integration Benefits

• More accurate search results
  Combines facet filtering with relevance ranking, avoiding lists in arbitrary chronological order.
• Fewer empty searches
  Typo tolerance reduces cases where the visitor gets “no results” due to a swapped letter.
• Smooth discovery experience
  Visitors refine text searches with side filters without losing the relevance of results.
• Reusing existing infrastructure
  Anyone already using FacetWP and Relevanssi separately can have them work together without custom code.

Who Is It For?

• WooCommerce stores with extensive catalogs that rely on combined text search and attribute filters.
• Content sites, portals, and magazines that need relevant search crossed with category and tag facets.
• Directories, listings, and listing platforms where search accuracy directly impacts navigation.

For projects that already use FacetWP as a filtering layer and Relevanssi as a search engine, this add-on removes the need for manual hooks to make the two work together. The practical gain is a filtered search experience with real relevance ranking—ideal for dense catalogs, content libraries, and directories where sorting by date simply isn’t enough.
