Ajax Search Pro is a WordPress plugin that replaces the default WordPress search box with a live, AJAX-driven search and filtering engine. It returns results as the visitor types, across posts, pages, custom post types, taxonomies, users, and media, and it adds a drag-and-drop builder for category, tag, and custom field filters. The plugin is sold on CodeCanyon for $139 and is aimed at site owners, freelancers, and agencies running content-heavy or e-commerce WordPress sites where the built-in search is not good enough. Ajax Search Pro Utilities sit in the same category as faceted navigation extensions: tools that turn a single keyword box into a structured discovery interface.
What Ajax Search Pro actually does beyond a standard search box
The core function is a live results panel that updates while the visitor types, without a page reload. Results can display images pulled from the featured image, post content, excerpt, or a custom field, which makes the dropdown look closer to a product carousel than a list of links. The plugin can also take over the theme’s own search results page, so the AJAX behaviour carries through after the visitor presses enter.
The more consequential feature is the filter builder. It uses a drag-and-drop interface to assemble taxonomy and custom field filters, with checkbox, radio, dropdown, multiselect, and date input types. Each filter exposes settings for ordering, which items are pre-selected, parent-child relationships, layout mode, and the logic that connects one filter to another. That last point matters: a filter that narrows results only after another filter is applied behaves very differently from one that always applies, and the plugin lets that relationship be defined rather than assumed.
Content coverage is broad. The search can return WooCommerce products, bbPress forums, topics and replies, BuddyPress groups and activity entries, custom taxonomy terms, and users, in addition to ordinary posts and pages. Media attachments are searchable too, and the plugin states it can index the contents of PDF, CSV, TXT, RTF, and Office documents. On a multisite network, each search instance can be pointed at a chosen set of blogs, and a single search can span several blogs at once.
Presentation is handled by four layouts — vertical, horizontal, polaroid, and isotopic — each with a set of pre-built themes, totalling more than sixty. The vendor supplies colourisable SVG icons, with the option to upload custom ones. Search logic defaults to OR matching, which returns more results, and can be switched to stricter matching. There is also an index table mode for relevance tuning, plus a frontend settings panel that lets visitors toggle things like exact match and post type inclusion themselves. Keyword suggestions and autocomplete are enabled out of the box.
Where this plugin fits, and where it does not
The clearest fit is a WooCommerce or Easy Digital Downloads store with a large catalogue. Once a shop passes a few hundred products, category browsing alone stops working, and shoppers expect to narrow by attributes. Ajax Search Pro’s custom field filters map directly onto product attributes, and its WooCommerce compatibility is explicitly listed for versions 5.x through 8.x. A store selling technical goods with size, material, or compatibility filters is the strongest use case.
A second fit is a content site with a deep archive: a documentation hub, a recipes site, a directory, or a magazine with thousands of posts across many categories. The taxonomy filters and relevance index give editors a way to surface older material that would otherwise be buried. Membership and community sites running BuddyPress or bbPress are also covered, since groups, forums, and replies can all appear as results.
Agencies and freelancers building client sites will get value from the page builder integrations. Shortcodes and widgets are declared compatible with Elementor, Elementor Pro, WPBakery Page Builder, Visual Composer, Beaver Builder, Divi, Cornerstone, Layers WP, and Gutenberg, and the plugin acts as an add-on inside some of them. WPML support means multilingual sites can be handled without a separate bridging plugin.
Where it is the wrong choice: a small brochure site with twenty pages and a blog. The default WordPress search is adequate at that scale, and the configuration surface here — hundreds of backend options, filter logic, index tables — is effort that will never pay off. A site with no custom post types, no taxonomies worth filtering, and no e-commerce component should look elsewhere or keep the built-in search.
Strengths and limitations
Strengths
- Genuinely broad content coverage: posts, pages, custom post types, taxonomy terms, users, BuddyPress groups and activity, plus searchable document attachments.
- The filter builder supports date and multiselect inputs, not just checkboxes and dropdowns, which covers most real filtering requirements without custom code.
- Four layouts and a large theme library reduce the amount of CSS work needed to make the search box match a site’s design.
- Multisite network search across selected blogs is built in rather than bolted on.
- Frontend settings let visitors adjust search behaviour themselves, which reduces support requests on large catalogues.
- Source files are included (JavaScript, CSS, PHP), so developers can extend or restyle the plugin rather than working around it.
- Strong track record: 23,005 sales and a 4.84 out of 5 rating across 1,029 reviews, with the vendor, wpdreams, updating the plugin regularly.
Limitations
- The backend is dense. The vendor describes over 400 options, and the filter builder adds its own settings on top. Teams without someone comfortable in WordPress admin will spend real time configuring rather than shipping.
- At $139 it is priced well above most search plugins on CodeCanyon. That is defensible for a store with thousands of SKUs and hard to justify for a five-page site.
- Index table search, which the vendor positions as the route to more relevant results, requires building and maintaining indexes. That is an ongoing operational task, not a one-time setting.
- Document content search depends on server-side text extraction, and the vendor does not publish limits on file size, index scope, or which languages are handled reliably.
- Support is stated as a 48-hour response window, usually 12 hours, with weekends excluded. That is reasonable for a marketplace plugin but not a same-day SLA.
- The compatibility list names specific WordPress and WooCommerce version ranges. Sites running beta releases or heavily customised installs should verify against a staging copy first.
How it compares with other WordPress search options
The alternatives fall into three groups. The first is the default WordPress search, which matches titles and content with a single query and offers no filtering, no live results, and no control over ordering. It costs nothing and is entirely adequate for small sites.
The second group is hosted search services, where the index lives on an external platform and the site queries it through an API. These typically deliver strong relevance and handle very large content sets well, but they introduce a recurring monthly cost, a third-party dependency, and a data flow off the site — a problem for privacy-sensitive projects or anyone who wants search to keep working if the external service has an outage.
The third group is other self-hosted WordPress search plugins. Most of these focus on improving relevance or on replacing the results page, and relatively few ship a full filter builder with date and multiselect inputs, multisite blog selection, and BuddyPress coverage in one package. Ajax Search Pro’s advantage is breadth: it is one plugin covering frontend live search, faceted filtering, custom post types, and community content. Its disadvantage is the same breadth — it carries more configuration weight than a plugin that only improves relevance, and it costs more.
Frequently Asked Questions
Does Ajax Search Pro work with WooCommerce product attributes?
Yes. Product attributes are stored as custom fields and taxonomies, and the plugin’s filter builder supports both taxonomy term filters and custom field filters. That means filters can be built for attributes such as size, colour, or brand, with checkbox, dropdown, radio, multiselect, or date input types. WooCommerce versions 5.x through 8.x are listed as compatible.
Can Ajax Search Pro search PDF and Office documents?
Yes, the vendor states that media attachments can be searched including their content, covering PDF, CSV, TXT, RTF, and Office, Excel, and PowerPoint files. The plugin does not publish details on file size limits, indexing depth, or language handling for document extraction, so testing against a representative sample of files is advisable before relying on it.
Is Ajax Search Pro compatible with Elementor and other page builders?
Yes. Shortcodes and widgets are declared compatible with Elementor, Elementor Pro, WPBakery Page Builder, Visual Composer, Beaver Builder, Divi, Cornerstone, Layers WP, and Gutenberg. The plugin also functions as an Elementor live posts and products widget filter, and a custom results page can be built inside Elementor. Shortcode buttons appear in the post editor.
Does Ajax Search Pro replace the default WordPress search results page?
Yes, it can. The plugin offers a setting that overrides the theme’s default search results, extending the AJAX behaviour to the results page rather than only the dropdown. A live results page loader script is included for this purpose. The override is optional, so the default results page can be retained if preferred.
Verdict
Ajax Search Pro earns its price on sites where search is a primary navigation path rather than a fallback: WooCommerce stores with large catalogues, directories, documentation hubs, and community sites running BuddyPress or bbPress. The combination of live results, a real filter builder, multisite support, and broad content type coverage is difficult to assemble from separate plugins, and the sales and rating figures suggest it holds up in production. Buyers should go in expecting a configuration project, not a five-minute install, and should budget time for index table setup if relevance tuning matters. Site owners running a small brochure site or a simple blog should keep the default WordPress search and spend the money elsewhere.
