FalcoSearch – Live Search & Product Filter for WooCommerce

FalcoSearch is a free WordPress plugin that adds live AJAX search and product filters to a site. Visitors get results while typing, and can filter WooCommerce products or any post type by category, price, rating, stock and other attributes without reloading the page.

Yes. FalcoSearch is free and open source (GPLv2 or later). Every feature described on this page is included in the free plugin.

WordPress 5.2 or newer and PHP 7.4 or newer. WooCommerce is optional and only needed for product search and product filters. No other plugin or external service is required.

A few minutes. Search works after activation. For filters, choose Set up shop filters for me and FalcoSearch creates a filter set from your categories, prices and product attributes and places it on your shop pages.

Yes. Enable Products in the search settings and results show the product image, price, sale badge and stock status. The filter builder supports product categories, tags, attributes, price, rating, and availability such as in stock and on sale.

Yes. WooCommerce is optional. Live search and filters work for posts, pages and any public custom post type. WooCommerce-only options, such as price sorting and availability toggles, appear only when WooCommerce is active.

Add the shortcode [xerosf_icon] for a search button or [xerosf_input] for a search field, in any page, widget or template. FalcoSearch can also open from your theme's existing search field, from Ctrl + /, or from a triple-click — each can be switched on or off under Triggers.

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: the visitor types and matching products or posts appear instantly. Product filters (also called faceted search or layered navigation) narrow a list the visitor is already looking at — for example a shop page — by category, price, color, size, brand, rating or stock. FalcoSearch includes both, and they can be used together or separately.

No. FalcoSearch adds a live search window on top of your site and can open it from your theme's existing search field. Your normal search results page keeps working, and filter sets can be shown on it.

Yes. The two parts are independent. Turn off the search triggers to use filters alone, or simply create no filter sets to use search alone. Scripts and styles load only for the part that is in use.

Yes. Use a range slider or min / max inputs for price, and checkboxes, buttons, dropdowns or swatches for any product attribute or taxonomy such as color, size or brand. Swatch colors and images are set on each term's edit screen.

Yes. Each option shows how many results it would give with the current selection, options that would give nothing can be hidden, and counts refresh after every change.

Yes. 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. You choose how many taxonomy filters deep a page may be indexed. Pages filtered by price, stock, rating, date or sort order are marked noindex,follow to avoid duplicate content.

Yes. FalcoSearch adds Filters, Chips and Sorting widgets to Elementor. On block themes it filters the WooCommerce Product Collection block. Classic themes are supported through WooCommerce and WordPress template hooks.

Yes. Live search works on pages served from a full-page cache. For filtered pages that share a URL, an optional cookie lets Cloudflare, Varnish, Nginx, WP Rocket, W3 Total Cache and Batcache keep separate cached copies.

It is built to stay light. The front end uses vanilla JavaScript with no jQuery, scripts load only on pages that need them, voice search and slash commands load on first use, and search results and filter counts are cached.

Yes. All interface text is translatable (text domain wpxero-search-filter). With WPML or Polylang, filter labels can be translated and filters use the terms of the current language.

Yes. Price filters convert between the shop's base currency and the visitor's currency. WOOCS and CURCY are supported out of the box; other currency plugins can connect through two filters.

FalcoSearch does not send data to any third-party service. If you turn on search analytics, each search term, its result count, the time, and the WordPress user ID of a logged-in user are saved in your own database for the retention period you choose (90 days by default). Favorites and recent searches stay in the visitor's browser. The only outgoing requests are to the cross-site search endpoints you add yourself, if any.

Turn on analytics in the settings, then open FalcoSearch → Analytics. It shows total searches, top keywords, searches with no results, volume over time, and offers a CSV export.

Yes. Developers can adjust the weight of title, excerpt, content, taxonomy and meta matches with the xerosf_weights filter, and reorder or edit results with xerosf_results.

Usually not — settings, shortcodes, hooks and filter sets are kept. Check three settings that are now applied exactly as set: Show excerpt in results (off by default), Search mode ("Title only" now searches titles only) and Enable slash commands (off by default). On WooCommerce archives, vertical filter sets now appear as a sidebar beside the products.

Partly. Checkbox, radio, dropdown, rating, date and min / max filters submit as a normal form and reload the page. Range sliders, buttons and swatches need JavaScript.

Yes. FalcoSearch is the new name of Xero Finder. The plugin slug, settings, shortcodes and hooks are the same, so updating does not require any changes.

Turn on Remove all data on uninstall under Privacy & data, then delete the plugin. This removes the settings, filter sets, cached data and the analytics table. With the option off, deleting the plugin keeps your data.
