Relevanssi is the most popular WordPress search replacement plugin with over 100,000 active installations and 1.6 million downloads. It has been available since 2008 and is maintained by a dedicated developer (Mikael Saari).
Relevanssi replaces default WordPress search with a keyword-based engine that sorts results by relevance instead of date. It adds fuzzy matching (finds "pizza" when you type "pizzas"), custom field indexing (WooCommerce SKUs, ACF fields), search term highlighting, and configurable relevance weights. The Premium version ($119/year) adds PDF search, multisite support, and advanced features.
Relevanssi is excellent at what it does: making keyword search much better. But it does not offer semantic or AI-powered search. If a customer searches "gift for dad who likes cooking," Relevanssi will not find results unless products contain those exact words.
Queryra is an AI-powered semantic search plugin built for WordPress and WooCommerce. Instead of improving keyword matching, Queryra replaces the entire search approach with vector-based AI that understands meaning.
When a customer searches "spa evening at home," Queryra finds bath oils, candles, and face masks — because the AI understands the concept, not just the words. No synonym configuration needed, no manual keyword setup. The AI learns from your actual product catalog.
Setup takes 5 minutes: install, paste one API key, sync products. $9.99/month after a 14-day free trial. No ChatGPT or OpenAI key needed — AI is included, so no surprise costs.
This is the fundamental difference between these two plugins.
Improves WordPress keyword search significantly. Indexes custom fields, adds fuzzy matching for typos, sorts by relevance using TF-IDF weighting. You can configure synonyms manually and adjust weights for titles vs content.
Converts products into AI vector embeddings that capture meaning. Queries are matched by semantic similarity. "Warm winter clothing" finds sweaters and jackets without any manual synonym configuration.
| Customer searches | Relevanssi | Queryra |
|---|---|---|
| "Cocolo Collagen Cream" | Exact match | Found |
| "collagen cream" | Partial match | Found |
| "something for wrinkles" | No match | Anti-aging products |
| "looking older than my age" | 0 results | 16 products |
| "gift for girlfriend birthday" | 0 results | 18 products |
| "spa evening at home" | 0 results | 39 products |
Bottom line: Relevanssi makes keyword search much better. Queryra makes search understand what customers mean.
Requires configuration: choose content types to index, set relevance weights, configure custom fields, optionally set up synonyms. Can require hundreds of MB of database space (3x wp_posts table).
Minimal configuration: install, paste API key, click sync. Products indexed in the cloud — no impact on database size. AI handles relevance automatically — no weights or synonyms to configure.
Bottom line: Relevanssi rewards configuration time. Queryra works immediately with zero configuration.
Bottom line: Relevanssi free is hard to beat on price. For AI semantic search at $120/year, Queryra matches Relevanssi Premium while offering fundamentally different technology.
Available since 2008 — nearly 18 years of development. 100,000+ active installations, hundreds of 4.5+ star reviews, extensive documentation. Battle-tested on sites with tens of thousands of posts.
Launched January 2026. New product with modern AI technology. Impressive search results, but doesn't have the track record that Relevanssi has built over nearly two decades.
Bottom line: If track record and stability are your top priority, Relevanssi is the safe choice. If you want AI-powered natural language search, Queryra offers technology that Relevanssi doesn't.
Both plugins work by hooking into WordPress search at the core level, leaving your theme templates unchanged.
Widely compatible but some themes with query_posts() can cause issues. Requires significant database space that may be a problem on shared hosting.
Hooks into posts_search and posts_orderby filters only, with zero database impact (indexing in cloud). Works with every WordPress theme including Flatsome, Storefront, Astra, OceanWP.
No — both plugins replace WordPress default search, so you should choose one. If you're currently using Relevanssi and want to try AI semantic search, install Queryra's 14-day free trial. You can deactivate Relevanssi temporarily to test, and switch back if you prefer keyword search.
AI-powered semantic search was only available to enterprises with deep pockets — Algolia, Elasticsearch, custom ML pipelines. Small WooCommerce stores had two options: expensive enterprise solutions or building their own with OpenAI APIs.
The cost barrier is real. Enterprise AI search solutions like Algolia cost $50-500/month. Building your own with OpenAI APIs can easily exceed $1,000/month even with moderate traffic and many search queries. Queryra delivers the same AI technology for $9.99/month.
We built Queryra to democratize AI semantic search. One plugin, one API key, flat pricing. No enterprise sales calls, no OpenAI billing surprises, no ML expertise required.
Try AI semantic search yourself. Type natural language queries and see how Queryra understands meaning, not just keywords.
They solve different problems. Relevanssi makes keyword search excellent — it's the best keyword search plugin for WordPress with 100,000+ installations. Queryra uses AI semantic search to understand customer intent, finding relevant products even when queries don't contain matching keywords. If your customers search by product name, Relevanssi is great. If they describe what they want in natural language, Queryra finds what they mean.
Yes. Install Queryra, sync your products, and enable AI search. Deactivate Relevanssi. Because both plugins use standard WordPress hooks, no theme changes are needed. The switch takes about 5 minutes.
No. Relevanssi is a keyword-based search engine. It improves keyword matching with fuzzy search, synonyms, and relevance scoring, but does not understand natural language or customer intent. For AI semantic search, you need a plugin like Queryra.
Relevanssi's free version is free. Relevanssi Premium costs $119.83/year. Queryra costs $9.99/month ($120/year) after a 14-day free trial. If you need only better keyword matching, Relevanssi free is the cheapest option. If you want AI semantic search, Queryra and Relevanssi Premium are similar in annual cost.
