1. The options at a glance
Active installations on WordPress.org, 2 November 2026: FiboSearch 100,000+, Relevanssi 100,000+, Advanced Woo Search 60,000+, Smart WooCommerce Search 5,000+, Doofinder 2,000+. The first four run inside your WordPress installation and use your database. Doofinder and Grumeria are hosted services: the index runs on their servers and your store sends product data to them.
Installations show how widely a plugin is used, not whether it finds the right products in your shop. Test every candidate with your own queries, see section 4.
2. What each plugin offers, free and paid
FiboSearch (formerly Ajax Search for WooCommerce) adds a search bar with live suggestions. The free version searches the product title, long and short description and lists “Search by SKU”. Fuzzy search (“works even with minor typos”), search in attributes and search by variation SKU are listed as Pro features, together with an inverted index search engine that, according to the page, “works up to 10× faster than the Free version”.
Advanced Woo Search can search the title, content, excerpt, categories, tags, ID and SKU in the free version and lists synonyms, plurals, stop words and “Automatic misspelling correction ( fuzzy search )” as built in features. Search by product attributes such as colour or size and search by GTIN, UPC or EAN are PRO features.
Relevanssi “replaces the standard WordPress search with a better search engine” and sorts results by relevance. Its fuzzy matching matches partial words. It is a general WordPress search, not a WooCommerce plugin, and its page warns that it “may require large amounts (hundreds of megabytes) of database space”. Improved spelling correction in “Did you mean?” suggestions is a Premium feature.
Smart WooCommerce Search lists search by SKU or EAN, a fullscreen popup and a GA4 integration as free features. Internal analytics with “no-results phrases”, “Did you mean” and synonyms are PRO features.
3. Hosted search: Doofinder and Grumeria
Doofinder's WooCommerce plugin connects the store to Doofinder's hosted search. Its WordPress.org page lists product filters, rules to prioritise products, voice and image search, real time analytics and “Typo-Tolerance & Synonyms”. Our Doofinder comparison lists its plans and prices.
Grumeria connects with a product feed and a small widget. The feed can come straight from your store's public product data via https://grumeria.com/api/woocommerce-feed?shop=your-shop.com, so no feed plugin is needed. Typo tolerance, synonyms, filters, ranking rules and search statistics with a list of searches without results are part of every plan. The index runs in Frankfurt, the search works without cookies and search queries do not run on your WordPress database. Plans start at €29 per month excl. VAT for 2,000 products, with a 14-day trial without a payment method. Grumeria does not offer voice or image search.
4. How to choose: test with your own catalogue
A small catalogue where shoppers search by product name is often fine with a free plugin. If shoppers search by SKU, colour or size, check whether that search is in the free or the paid version. If your catalogue is large or your hosting is slow, look at how the plugin indexes and how much database space it needs, or use a hosted search.
Install each candidate on a staging copy, run the same queries and note whether the expected product is among the first results.
- Take ten real queries from your shop, including two with typos, one SKU and one with a colour or size.
- Run them with the default search, then with each plugin on a staging copy.
- Check variations: does the SKU of a single variation lead to the right product?
- Check load: search speed on mobile and the database size after indexing.
- Check the list of searches without results after a week of real traffic.
Example test set
“bluetooth speakr” (typo) · “speaker” (part of a longer name) · “BT-200-BLK” (SKU) · “speaker black” (name and colour).
Frequently asked questions
Which WooCommerce search plugins handle typos?
According to their WordPress.org pages, Advanced Woo Search includes misspelling correction (fuzzy search) in the free version. FiboSearch lists fuzzy search as a Pro feature. Relevanssi matches partial words; improved spelling correction is in Relevanssi Premium. Hosted services such as Doofinder and Grumeria include typo tolerance.
Can WooCommerce search by SKU without a plugin?
No. The storefront search uses the WordPress search, which looks at the title, excerpt and content. FiboSearch, Advanced Woo Search and Smart WooCommerce Search add SKU search in their free versions.
Do search plugins slow down my store?
Plugins that run inside WordPress use your database and server. Relevanssi warns that its index may need hundreds of megabytes of database space. Hosted search runs on the provider's servers instead.
