FalcoSearch
Live search & product filter for WooCommerce
Live AJAX search and a visual product filter builder for WooCommerce and any post type, with SEO-friendly filter URLs and no jQuery.
- Free on WordPress.org
- Version 1.2.0, updated Oct 5, 2026
What is FalcoSearch?
FalcoSearch adds instant live search and AJAX product filters to a WooCommerce store or any WordPress site. Visitors see matching products and posts while they type, then narrow a shop or archive page by category, price, rating, availability and more without a page reload. It combines two tools that are usually separate plugins: a live search window with prices, sale badges and highlighted matches, and a drag-and-drop filter builder with 12 filter types, live counts and clean, indexable filter URLs. One click builds a ready-made filter set from your store's own categories, prices and attributes. FalcoSearch also records what visitors search for and which searches find nothing. It works with posts, pages and any public post type, on classic and block themes and in Elementor, uses vanilla JavaScript and loads its files only where they are needed. FalcoSearch was formerly called Xero Finder.

AJAX Filtering With Live Counts

Frequently Asked Questions
Everything you need to know about FalcoSearch
Yes. FalcoSearch is free and open source (GPLv2 or later). Every feature is included in the free plugin.
Yes. WooCommerce is optional. Live search and filters work for posts, pages and any public custom post type; WooCommerce-only options appear only when WooCommerce is active.
Go to FalcoSearch → Filter Sets, click New Filter Set and choose Set up shop filters for me. The filters appear in a sidebar on your shop, category and tag pages. To place a set yourself, use [xerosf_filters set="ID"] or the FalcoSearch Filters widget in Elementor.
Live search finds items by keyword as the visitor types. Product filters — also called faceted search or layered navigation — narrow a list the visitor is already looking at by category, price, colour, size, brand, rating or stock. FalcoSearch includes both, and they work together or separately.
Filter sets can use clean URLs such as /shop/color-blue/ with their own title, H1 and meta description templates, canonical tags and sitemap entries. Pages filtered by price, stock, rating, date or sort order are marked noindex,follow to avoid duplicate content.
Yes. Live search works on pages served from a full-page cache, and an optional cookie lets Cloudflare, Varnish, Nginx, WP Rocket, W3 Total Cache and Batcache keep separate cached copies of filtered pages.
It sends nothing to third-party services. If you turn on search analytics, search terms, result counts, times and logged-in user IDs are stored in your own database for the retention period you choose (90 days by default). Favorites and recent searches stay in the visitor's browser.
Yes. FalcoSearch is the new name of Xero Finder. The plugin slug, settings, shortcodes and hooks are the same.
