How to Improve WordPress Search: Plugins, Configuration, and WooCommerce Search
Default WordPress search misses custom fields, ranks poorly, and cannot search WooCommerce products properly. Here is every method for making WordPress search actually work.
WordPress ships with a basic search function that queries post titles and content. For most sites this is inadequate — it cannot search product attributes, custom fields, file attachments, or relevance-rank results effectively. Here is how to configure WordPress search correctly for your site type.
The limitations of WordPress default search
- Searches only post title and post content — ignores custom fields, meta descriptions, categories, tags, and taxonomies
- Returns results in reverse chronological order, not by relevance
- Does not support fuzzy matching — a search for ‘optimise’ will not find ‘optimization’
- Does not search media attachments, pages (by default), or custom post type content unless configured
- No autocomplete or search suggestions
- WooCommerce products: default search does not search product SKUs, attributes, or short descriptions
If your site has fewer than 50 posts and visitors primarily browse by category, WordPress’s default search is functional. The improvements below become increasingly important as your content library grows and as your audience uses search more actively.
Method 1 — SearchWP (paid, most powerful)
SearchWP is the most capable search plugin for WordPress. It replaces the default search engine with one that indexes everything: custom fields, taxonomies, file contents, WooCommerce product data, and Relevanssi-style relevance ranking.
- Price: from $99/year for a single site
- Indexes ACF custom fields, post meta, taxonomies, and media files
- Full WooCommerce integration: searches SKUs, attributes, product descriptions, and reviews
- Relevance scoring: results ranked by how well they match the query, not just publication date
- Fuzzy matching and partial word matching
- Custom search forms and AJAX-powered autocomplete
Method 2 — Relevanssi (free / premium)
Relevanssi is a free plugin that significantly improves WordPress search relevance without SearchWP’s full feature set. It is a good middle ground for sites that need better search without the premium cost.
- Replaces the default relevance algorithm with phrase matching and word weight customisation
- Searches custom fields and taxonomies (configuration required)
- Fuzzy matching via a separate Relevanssi Fuzzy Matching extension
- Highlights search terms in results
- Logs search queries so you can see what your visitors are searching for
- Free for single sites; Relevanssi Premium adds custom field indexing and better WooCommerce support
Method 3 — Algolia (enterprise-grade)
Algolia is a hosted search-as-a-service platform that delivers instant, typo-tolerant, faceted search results. The WP Search with Algolia plugin connects your WordPress content to Algolia’s search infrastructure.
- Best for: large content libraries, high search volume, e-commerce sites needing faceted search
- Sub-10ms search response times — results appear as the user types
- Typo tolerance: finds results even with spelling errors
- Faceted search: filter results by category, tag, price range, attribute
- Price: free tier up to 10,000 records and 10,000 searches/month; paid from $0.50 per 1,000 additional searches
Method 4 — Elasticsearch via ElasticPress
ElasticPress connects WordPress to an Elasticsearch server — the same search technology used by Wikipedia, GitHub, and Shopify. It is the most powerful option for very large sites but requires an Elasticsearch server (hosted via ElasticPress.io or ElasticCloud).
Unless you have tens of thousands of posts or require advanced faceted search with sub-second performance, SearchWP or Relevanssi will serve you equally well at a fraction of the cost and complexity.
Improving the default search results page
Even with improved search indexing, the default search results page template is minimal. Improve it by:
Add a search.php file to your child theme directory. This template controls how search results are displayed. Copy the closest template from your parent theme and modify it.
Show the visitor how many results were found and allow sorting by date, relevance, or custom criteria.
The default search results page shows text only. Adding featured images to search results significantly improves the visual experience and click-through on results.
Customise the no results state to suggest categories, popular content, or offer to search again. A generic ‘nothing found’ message is a dead end.
WooCommerce search optimisation
WooCommerce product search has specific requirements beyond standard WordPress search:
- Search by SKU: customers often know the product code. Enable SKU search via SearchWP WooCommerce integration or the Search by SKU for WooCommerce plugin
- Search by product attribute: colour, size, material — SearchWP and WooCommerce Search Filters handle this
- Live search autocomplete: show product thumbnails and prices in a dropdown as the customer types. AJAX Live Search for WooCommerce adds this without SearchWP
- Redirect single-result searches directly to the product page rather than showing a one-item results page

Frequently asked questions
Should I add a search bar to my WordPress site?+
Yes if your site has more than 30-50 pieces of content and visitors have a specific information need. Navigation works well for sites where visitors browse by category; search works well for sites where visitors come with a specific question or product in mind. For content-heavy sites, blogs, and WooCommerce stores, search is a high-value navigation tool. For simple brochure sites with 5-10 pages, navigation alone is sufficient.
Does site search affect SEO?+
Site search itself does not affect your external SEO rankings. However, the search results pages WordPress generates (e.g. /?s=keyword) can create thin content pages that Google may index negatively. Add a noindex meta tag to search results pages using your SEO plugin (Rank Math: Appearance › Search › disable indexing of search pages). Monitor your Search Console for search result URL indexing issues.
How do I see what my visitors are searching for?+
Relevanssi logs all site searches in its dashboard. SearchWP has a similar built-in log. Alternatively, enable site search tracking in Google Analytics 4: go to Admin › Data Streams › Enhanced Measurement › enable Site Search. This captures the search term parameter from your search URLs (typically the ‘s’ parameter) and reports them in GA4’s Events reports.
