Frequently Asked Questions

Common questions about CelerSearch – AI-Powered Instant Search with Meilisearch

Yes. Two options: Self-host on your VPS: free, but you handle updates, backups, and SSL. Upstream guide. Managed at celersearch.com: from $12/mo, provisioned in seconds, updates and backups handled.

Three, all running this plugin with AI Semantic Search enabled: an Outdoor Shop (WooCommerce), an Art Gallery (custom post type), and a Cinema. Overview at celersearch.com/demos.

Meaning-aware search. CelerSearch stores a vector embedding for each document and blends semantic similarity with keyword relevance on every query (hybrid search). Searching for keep my coffee hot on the summit surfaces a vacuum flask even though its copy never contains those words. It is optional and enabled per index; with it off, keyword search works exactly as before.

Only for AI Semantic Search. Regular keyword search never calls any AI service. You enter the key per index (Index Settings, AI Search); it is stored server-side, shown masked, used only to generate embeddings, and never exposed to visitors.

OpenAI's text-embedding-3-small (the default: 1536 dimensions, fastest and cheapest) and text-embedding-3-large (3072 dimensions, most accurate). Developers can register other embedding sources via the celersearch_embedder_sources filter.

You pay OpenAI directly, per token, on your own API key. CelerSearch makes one embedding call per document at index time (and again when a document changes), plus one per search query. At the default model's $0.02 per 1M tokens (OpenAI pricing as of mid-2026; text-embedding-3-large is $0.13) that stays small: indexing 10,000 typical products costs roughly $0.05 to $0.15 one time, and 100,000 searches cost a few cents. Each document's embedded text is capped by the Template max bytes setting (default 3000 bytes, roughly 750 tokens), so costs are bounded. Set the semantic ratio to 0 and no embedding calls are made at all.

No. It works with any Meilisearch 1.13 or newer (or 1.3+ with the vectorStore experimental flag), self-hosted included. The CelerSearch Cloud AI plans are simply sized for vector search workloads.

Yes, once. Embeddings are generated at index time, so after enabling AI Search run a rebuild; from then on, new and edited content is embedded automatically as it syncs. Every index-settings tab shows an impact badge telling you whether a change applies instantly or needs a rebuild.

An optional assistant that answers visitor questions in natural language, using your indexed content. For each question it retrieves the most relevant documents from the index, has an AI model compose a short answer from them, and streams the reply live with numbered sources. Place it as a floating widget on the pages you choose, inline with the [celersearch_chatbot] shortcode, or via the Chatbot block.

Semantic search improves the ranked result lists your visitors already use (search page, autocomplete, shop filters). The chatbot answers questions conversationally instead of returning a list. They are independent features: use either, both, or neither.
