When visitors land on your WordPress site and use the search bar, two things matter: the quality of results and the speed of the experience. Most WordPress search improvement plugins focus on one of these, rarely both. That’s the fundamental distinction between SearchWP and Ajax Search Pro.
SearchWP is an indexing and relevance engine. It replaces WordPress’s weak default search backend with a powerful, configurable index that understands custom fields, WooCommerce products, ACF data, and more. Ajax Search Pro is primarily a front-end live search experience, as you type, beautifully styled results drop down in real time, with drag-and-drop layout customization. Two different jobs. Two different tools.
Interestingly, the two plugins can actually work together, Ajax Search Pro as the live search UI, SearchWP as the index powering the results. But most site owners are choosing between them as standalone replacements for the default search. This comparison breaks down exactly what each does best, where each falls short, and which one matches your site’s needs.
⚡ Quick Verdict
- →Pick SearchWP if you need a robust search index with relevance tuning, WooCommerce integration, custom field search, and developer control over what gets indexed and how results rank.
- →Pick Ajax Search Pro if your priority is a visually stunning, real-time autocomplete search experience with drag-and-drop result layout customization and a lower one-time price point.
📋 Table of Contents
SearchWP Overview
SearchWP is a premium WordPress search plugin built around a proprietary indexing engine. It replaces the default WordPress search backend entirely, building its own index of your content across posts, pages, custom post types, custom fields, WooCommerce products, and uploaded documents. You configure “search engines”, named instances with specific post types and relevance weights, giving you precise control over what gets searched and how results rank. Extensions add WooCommerce SKU search, ACF field indexing, PDF content extraction, and more. For sites with complex content structures, SearchWP is among the best WordPress search plugins available today.
Ajax Search Pro Overview
Ajax Search Pro is a premium WordPress plugin sold on CodeCanyon (Envato marketplace) that focuses on delivering a beautiful live search experience. As users type, results appear instantly in a styled dropdown, with thumbnails, post type labels, custom result layouts, and configurable columns. It has its own search backend that queries the WordPress database via AJAX, but its strength is the front-end UX rather than deep indexing capabilities. The plugin is highly visual: layout templates, color scheme controls, and a drag-and-drop result builder let non-developers create polished search interfaces without code.
Pricing Compared
The pricing models here are quite different. SearchWP is subscription-based, starting at $99/year for a Standard single-site license. The Pro plan (multiple sites) runs higher, and the Agency plan at $299/year covers unlimited sites, strong value for agencies managing client installs.
Ajax Search Pro is sold as a one-time purchase on CodeCanyon, with a regular license at approximately $36 (single site). An extended license is available for sites that charge users or resellers. The one-time pricing is appealing for budget-conscious buyers, though it means updates beyond the included support period may require purchasing a renewal.
If you’re comparing total cost over two to three years, SearchWP’s annual subscription can add up, but it covers ongoing index improvements, new extensions, and dedicated support. Ajax Search Pro’s one-time cost looks compelling at first, but factor in that the backend search quality is not as configurable as SearchWP’s indexing engine. For WooCommerce stores where search quality directly drives revenue, SearchWP’s annual cost is typically justifiable.
Search Indexing & Relevance Tuning
This is the biggest functional divide between the two plugins. SearchWP builds and maintains its own search index in dedicated database tables. You can tune relevance weights per field, give titles more weight than body content, boost specific custom fields, or demote certain post types. Synonyms, stop words, and keyword stemming are all configurable. Multiple named engines let you power different search bars on the same site with completely different configurations.
Ajax Search Pro queries the WordPress database live on each keystroke via AJAX. Results appear fast because the plugin is optimized for autocomplete latency, not deep indexing. Relevance tuning is more limited, you can filter by post type and select which fields to search, but there’s no weighted scoring system comparable to SearchWP’s engine configuration. For pure result quality on sites with complex content, SearchWP wins this category cleanly.
WooCommerce & Custom Post Type Support
SearchWP’s WooCommerce extension indexes product titles, descriptions, short descriptions, SKUs, custom attributes, and variation data. A customer searching by SKU or a specific attribute value will find the exact product. The extension integrates natively with WooCommerce’s search widget and the block-based product search block. For sites listed in the best WooCommerce search plugins roundup, SearchWP consistently ranks among the top options precisely because of this integration depth.
Ajax Search Pro supports WooCommerce product search in its autocomplete results, product thumbnails, titles, and prices appear in the dropdown. But it doesn’t index product attributes or SKUs with the same depth as SearchWP. For a store with complex product catalogs or custom attributes, Ajax Search Pro’s live results can look great while still returning incomplete results for specific queries. Custom post types are supported in both plugins, but SearchWP’s per-engine configuration gives more precise control.
Performance & Developer Tools
SearchWP’s independent index means search queries run against optimized custom tables rather than the main WP posts table. This improves database performance on high-traffic sites and removes search query overhead from page loads. The developer API is extensive: custom sources let you index arbitrary data, hooks let you modify results, and REST API support enables headless implementations.
Ajax Search Pro is built for low-latency live search, AJAX calls are optimized and the plugin uses request throttling to prevent query flooding as users type. The visual customization tools are strong: developers and non-developers alike can use the result layout builder to control what appears in search dropdowns. However, the API surface for programmatic customization is narrower than SearchWP’s. Teams building complex custom search experiences will hit the limits of Ajax Search Pro faster than SearchWP.

Get SearchWP →Frequently Asked Questions
Can SearchWP and Ajax Search Pro work together?
Yes, this is one of the more interesting setups in the WordPress search space. Ajax Search Pro can be configured to use SearchWP as its search backend, giving you Ajax Search Pro’s beautiful live search UI powered by SearchWP’s deep indexing engine. You get the visual autocomplete experience and the indexing quality in one setup.
Does Ajax Search Pro index custom fields?
Ajax Search Pro can be configured to search custom field keys in queries, but it doesn’t build a dedicated index the way SearchWP does. Custom field search results depend on live database queries, which are less optimized than SearchWP’s pre-built index for sites with large amounts of custom field data.
Is Ajax Search Pro a one-time purchase?
Yes. Ajax Search Pro is sold on CodeCanyon with a regular license (~$36) that covers a single end product. Updates are included for the support period. After that, you can continue using the version you have or purchase an extended support renewal. It’s a different model from SearchWP’s annual subscription.
Does SearchWP include a live search widget?
Yes. SearchWP includes live search functionality, as users type in the search field, results appear in a dropdown. The live search is powered by SearchWP’s index, so results benefit from all the relevance tuning and custom field indexing you’ve configured.
Which plugin is faster for live search?
Ajax Search Pro is optimized specifically for low-latency live search and generally shows results slightly faster than SearchWP’s live search mode. However, SearchWP’s live results are pulled from a pre-built index rather than live database queries, which means it scales better on high-traffic sites and large databases without slowing down as content grows.
Does Ajax Search Pro support WooCommerce?
Ajax Search Pro supports showing WooCommerce products in live search results, including product images, titles, and prices. However, it doesn’t index WooCommerce product attributes, SKUs, or variations with the depth that SearchWP’s dedicated WooCommerce extension provides.
Can I customize the look of SearchWP search results?
SearchWP’s live search results are styled with CSS and template overrides. It’s more developer-oriented than Ajax Search Pro’s drag-and-drop layout builder. If visual customization without code is your priority, Ajax Search Pro has the edge. If you have a developer on hand, SearchWP’s results can be styled precisely to your design system.
Is Ajax Search Pro good for non-WooCommerce sites?
Yes, Ajax Search Pro works well on standard WordPress sites, blogs, and membership communities where the goal is a fast, visual live search experience. If your site has simple post types and you don’t need deep relevance tuning, Ajax Search Pro’s visual strengths shine without needing SearchWP’s more complex engine configuration.
Does SearchWP support synonym search?
Yes. SearchWP includes built-in synonym support across all search engines. You define groups of synonyms, for example, “t-shirt” and “tee”, and SearchWP treats them as equivalent in search queries. Ajax Search Pro doesn’t offer comparable synonym configuration.
Which is better for a membership site?
SearchWP is generally the better choice for membership sites, particularly if content is gated across multiple custom post types. The ability to configure separate search engines per content type, and to index restricted content correctly, gives SearchWP a structural advantage for membership architectures built with plugins like MemberPress or Paid Memberships Pro.
Does Ajax Search Pro slow down my site?
Ajax Search Pro adds AJAX request overhead on keystroke events. On well-optimized servers, the impact is minimal. On shared hosting or high-traffic sites, frequent AJAX queries can increase server load. SearchWP’s pre-built index approach is generally more efficient at scale because queries hit optimized custom tables rather than running live searches against the posts table on every keystroke.
Is SearchWP worth $99/year vs Ajax Search Pro’s one-time cost?
For WooCommerce stores and sites with custom content architectures, yes, the indexing depth, relevance tuning, and extension ecosystem justify the annual cost. For simpler sites focused on visual live search UX without deep indexing requirements, Ajax Search Pro’s one-time purchase is strong value. Evaluate based on whether your search problem is primarily about result quality or search experience design.
Final Word
SearchWP and Ajax Search Pro solve different problems. If you need search that finds the right thing, buried in custom fields, product attributes, or custom post types, SearchWP is the clear choice. If you need search that looks beautiful and delivers instant autocomplete results, Ajax Search Pro delivers that better than most.
