Typesense – fast, typo-tolerant search engine for building delightful search experiences

Typesense is a typo tolerant search engine that delivers fast and relevant results out-of-the-box.

Typesense ranks search results using a simple tie-breaking sorting algorithm that can rely on one or more of:

  1. Text match score, exposed as a special _text_match field.
  2. User-defined indexed numerical fields.

You can use the open source InstantSearch.js library, along with our Typesense-InstantSearch-Adapter to build a plug-and-play full-featured search interface, with just a few lines of code.

This is free and open source software.

Features include:

  • Typo Tolerance – handles typographical errors elegantly, out-of-the-box.
  • Simple and Delightful – simple to set-up, integrate with, operate and scale.
  • Blazing Fast – architectured from the ground-up for low-latency (<50ms) instant searches.
  • Tunable Ranking – easy to tailor your search results to perfection.
  • Sorting – sort results based on a particular field at query time (helpful for features like “Sort by Price (asc)”).
  • Faceting & Filtering – drill down and deep dive into the results.
  • Grouping & Distinct: – group similar results together to show more variety.
  • Scoped API Keys: – generate API keys that only allow access to certain records.
  • Curation & Merchandising – boost particular records to a fixed position in the search results, to feature them.
  • Raft-based Clustering – setup a distributed cluster that is highly available.
  • High availability – add more nodes with no fuss and bother. Typesense uses the Raft consensus algorithm to manage the cluster and recover from node failures.
  • Seamless Version Upgrades – as new versions of Typesense are released, upgrading is as simple as swapping out the binary and restarting Typesense.
