Queryra vs Relevanssi: Do You Need AI Search or Is Keyword Search Enough?

Relevanssi is the default answer when someone asks "how do I fix WordPress search?" And for good reason — 100,000+ active installations, 1.6 million downloads, a genuinely useful free version, and over a decade of active development by Mikko Saari.

If you've ever replaced default WordPress search with something better, there's a good chance you used Relevanssi.

Queryra takes a different approach entirely. Instead of making keyword search smarter, it uses AI to understand what people mean — regardless of the words they use.

The real question isn't which plugin is better. It's whether your site needs keyword search done well, or whether your visitors search in ways that keywords can't handle.

Full disclosure: I'm the founder of Queryra. I'll be straightforward about where Relevanssi is the better choice.

WordPress default search is terrible. It only looks at titles and content, ignores custom fields, and sorts by date instead of relevance. Both Relevanssi and Queryra fix this — but in fundamentally different ways.

Relevanssi builds a custom index of your content in your WordPress database. It uses TF-IDF weighting (term frequency-inverse document frequency) to rank results by how relevant the keyword match is. You can configure weights for titles, content, custom fields, taxonomies, and more. It's intelligent keyword matching — the same approach Google used before they added AI.

Queryra converts your content and search queries into vector embeddings — numerical representations of meaning. When a customer searches, the AI finds content whose meaning is closest to the query, regardless of whether the exact words match. There's no keyword index. There's no TF-IDF. It's a fundamentally different technology.

The simplest way to understand the difference: Relevanssi asks "do these words match?" Queryra asks "do these meanings match?"

Relevanssi — Keyword search with relevance ranking. Free version with core features. Premium at $99-129/year (unlimited sites). 100,000+ active installs. Custom fields, PDF indexing, synonyms, fuzzy matching, search logging. Runs entirely on your server.

Queryra — AI semantic search with intent-aware query parsing. Free 14-day trial. $9.99/month. 10+ active installs. Natural language understanding, 50+ languages, price/brand filters from plain text. Requires cloud API connection.

The free version is genuinely good. Relevanssi's free tier isn't a teaser — it's a fully functional search plugin that dramatically improves default WordPress search. For blogs, content sites, and small stores that just need better keyword matching, the free version is often enough. Queryra's free trial expires after 14 days.

100,000+ installs means battle-tested. Relevanssi has been running on hundreds of thousands of sites across every imaginable WordPress configuration. Edge cases, theme conflicts, plugin compatibility — they've seen and fixed most of them. Queryra launched in January 2026.

Runs on your server. Relevanssi indexes everything in your WordPress database. Your content never leaves your hosting. No external API calls, no third-party dependency. Queryra sends your content to our cloud servers for AI processing. If data sovereignty matters to your business, Relevanssi keeps everything local.

PDF indexing. Relevanssi Premium can read and index the text inside PDF files attached to your posts. If your site has product manuals, spec sheets, or documentation in PDF format, visitors can search inside them. Queryra doesn't index PDFs.

Deep customization through code. Relevanssi has an extensive API with dozens of filters and hooks. Developers who want precise control over every aspect of search ranking can build exactly the search experience they need. It rewards technical investment with predictable, fine-tuned results.

Database space is your only cost. Beyond the optional Premium license, Relevanssi costs nothing to run — no API calls, no bandwidth charges, no per-search fees. The trade-off is database space: Relevanssi's index can be 2-3x the size of your wp_posts table. On a large site, that means hundreds of megabytes of additional database usage.

Multisite support. Relevanssi Premium can search across multiple sites in a WordPress multisite network. Queryra doesn't support multisite.

Proven WooCommerce integration. Relevanssi works well with WooCommerce — it can search SKUs, product attributes, custom fields, and handle product variations. It's been tested with thousands of WooCommerce stores over many years.

Natural language queries. A customer searches "something warm for winter evenings, not too expensive." Relevanssi looks for the words "warm," "winter," "evenings," and "expensive" in your products. If your product descriptions say "cozy fleece blanket" instead, there's no match. Queryra understands that "warm for winter evenings" and "cozy fleece blanket" are semantically related and returns the right result.

Intent-aware parsing. Queryra's second layer goes beyond semantic matching. It extracts structured intent from natural language: "headphones under $50, not Beats, sort by rating" becomes a semantic search with a price filter, brand exclusion, and sort preference — all parsed from plain text. Relevanssi can't extract structured data from free-text queries.

Zero synonym management. Relevanssi lets you add synonyms manually — mapping "couch" to "sofa," "laptop" to "notebook." It works, but you need to anticipate every variation. Queryra doesn't need synonyms because the AI inherently understands that these words mean the same thing.

Multilingual without plugins. Queryra's embedding model supports 50+ languages out of the box. A Spanish-speaking customer can search on an English store and find relevant products. Relevanssi needs WPML or Polylang for multilingual search, and synonyms must be configured per language.

No database bloat. Relevanssi requires significant database space — the documentation warns that the index can be 2-3x the size of your posts table. On shared hosting with limited database space, this can cause problems. Queryra stores the index on our servers, so your WordPress database stays clean.

Simpler setup. Install plugin, paste API key, click sync. Done in 5 minutes. Relevanssi needs you to build the index, configure weights for each field, decide which content types to include, and optionally set up synonyms, stopwords, and throttling. More power, but more configuration time.

The search experience gap. This is the fundamental advantage. On a WooCommerce store with 500+ products, customers don't search with precise keywords. They search with intent: "gift for dad," "something like AirPods but cheaper," "dress for beach wedding." Keyword search — no matter how well configured — can't bridge the gap between how customers think and how products are described. Semantic search can.

Try before you install. Relevanssi has no public demo. Despite 100,000+ active installations, there's no way to experience the search before installing it on your own site. We couldn't find a single public-facing store or site showcasing Relevanssi's search in action. Queryra has live demos you can try right now — search a real WooCommerce store or search 3,000+ Wikipedia articles. No signup, no install.

Consider a WooCommerce store selling home goods. Here are five real queries customers might type:

1. "coffee mug" — Both plugins return great results. Keywords match perfectly.

1. "something to keep my drink hot" — Relevanssi searches for "something," "keep," "drink," and "hot." Might find a thermos if the description mentions "hot." Queryra understands the intent and returns thermoses, insulated mugs, and travel cups.

1. "gift for someone who just moved" — Relevanssi finds nothing unless a product description contains "moved" or you've configured synonyms. Queryra connects "just moved" to housewarming gifts, kitchen essentials, and home décor.

1. "modern lamp, not floor standing, under $75" — Relevanssi can match "modern" and "lamp" but can't parse the negation ("not floor standing") or the price filter from text. Queryra handles all three: semantic match + exclusion + price filter.

1. "lámpara de mesa" (Spanish for "table lamp") — On an English-language store, Relevanssi returns nothing. Queryra returns table lamps because the AI understands meaning across languages.

The pattern: the more descriptive and natural the query, the bigger the gap between keyword and semantic search. For simple keyword queries, both work equally well.

Relevanssi:
- Free version: core features, WooCommerce basic support, unlimited use
- Premium Annual: ~$99-129/year, unlimited sites, PDF indexing, multisite, priority support
- Premium Permanent: ~$299-434, lifetime license, never pay again

- Starter: $9.99/month ($120/year), full WooCommerce support
- Enterprise: contact for larger catalogs
- Sandbox Club for unlimited testing

Relevanssi's free version is hard to beat if budget is the primary concern. For stores that need premium features, Relevanssi Premium costs roughly the same as Queryra annually — but they deliver very different search experiences.

Choose Relevanssi if:

You run a blog, content site, or knowledge base where visitors search with specific keywords. You want a free plugin that dramatically improves default WordPress search. You need PDF indexing or multisite search. You prefer everything running locally with no external API dependency. You have the technical skills to configure weights, synonyms, and custom fields. Your budget is zero and the free version covers your needs.

Choose Queryra if:

You run a WooCommerce store where product discovery directly impacts revenue. Your customers search with descriptive, natural language queries — not precise keywords. You don't want to build and maintain synonym lists for every product variation. You need multilingual search without additional plugins. You want AI to handle relevance automatically instead of manually configuring weights. You're willing to pay $9.99/month for search that understands customer intent.

Relevanssi is the most important search plugin in WordPress history. It proved that default search was broken and gave 100,000+ sites a real fix — many of them for free. If you run a content site and need better keyword search, install Relevanssi. Don't overthink it.

But keyword search has a ceiling. No amount of synonym configuration, weight tuning, or fuzzy matching can bridge the gap between "gift for someone who loves cooking" and a Le Creuset Dutch oven. That's not a Relevanssi limitation — it's a keyword search limitation.

Queryra exists for the stores where that ceiling matters. Where customers browse with intent, not keywords. Where a failed search means a lost sale, not just a frustrated reader.

If your visitors search with precise terms and you want proven reliability, Relevanssi is the right choice. If your customers describe what they want in their own words and expect your store to understand, Queryra is built for that.
