FacetWP adds faceted search and filtering to any WordPress post type, letting visitors narrow down content by multiple criteria simultaneously. When a user selects a filter — like a product category, price range, or attribute — the results update instantly via Ajax without page reload. Multiple filters work together: selecting “red” and “large” shows only items that match both. The plugin works with any post type including WooCommerce products, posts, and custom post types, and includes filter types for checkboxes, dropdowns, radio buttons, sliders, date ranges, and search fields. For sites with large content catalogs that need user-friendly filtering, FacetWP is the most developer-friendly option for adding search facets, more flexible than wpDataTables for content filtering and more lightweight than full Elasticsearch solutions like ElasticPress.
FacetWP uses indexed data stored in custom database tables for faster filter queries. It hooks into WP_Query to modify search parameters without altering your theme’s template files.

Frequently Asked Questions
Does FacetWP work with WooCommerce?
Yes. FacetWP includes dedicated WooCommerce integration with facet types for product categories, price ranges, attributes (color, size), stock status, and ratings. It works with both simple and variable products.
How does the indexing system work?
FacetWP maintains separate database tables that store pre-computed filter data. When a post is saved, FacetWP indexes its taxonomy terms and meta values. This indexed data allows filter queries to run much faster than querying the WordPress posts table directly.
Can I use FacetWP with custom post types?
Yes. FacetWP works with any public WordPress post type. You configure which post types, taxonomies, and custom fields to include in the index, and FacetWP generates filter widgets based on the available data.
Does FacetWP support Ajax pagination?
Yes. FacetWP includes a pager module that handles pagination through Ajax. Results update without page reload, and the URL updates to reflect the current filter state for bookmarking.
Is FacetWP compatible with caching plugins?
Yes. FacetWP is compatible with page caching plugins. The initial filter page load serves a cached version, and subsequent filter selections use Ajax to load results without full page reloads.
