LumoSearch combines BM25F relevance ranking, typo tolerance, and instant autocomplete in a single, easy-to-deploy search engine.
Industry-standard ranking algorithm that scores documents based on term frequency, inverse document frequency, and field-level boosting. Delivers highly relevant results out of the box without manual tuning.
Handles typos and misspellings gracefully using trigram-based similarity. Users find what they need even when they can't spell it correctly.
Sub-50ms prefix-based autocomplete for real-time search-as-you-type interfaces. Built on a dedicated prefix index for maximum speed.
A developer-first REST API that feels natural in any tech stack. Two endpoints: search and autocomplete. API keys for authentication. JSON in, JSON out.
Assign custom weights to different fields so titles matter more than body text, or tags rank higher than descriptions. Fine-tune relevance without changing your data.
Automatically identifies and returns the exact character positions of matching terms within your documents. Build search result snippets with precise highlighting.
API keys are hashed with SHA-256 before storage. Admin keys for management, scoped public keys for search. Keys are shown once at creation and never stored in plain text.
Deploy on LumoSearch Cloud and never think about servers. Automatic scaling, EU-hosted data, encrypted at rest and in transit. Focus on your product.
Track search volume, document counts, and API usage in real-time. Understand how your users search and when you need to scale.
