Typesense — Fast Typo-Tolerant Search Engine

What it is

Typesense is an open-source search engine built in C++ that delivers sub-50ms search results with typo tolerance out of the box. It provides faceted filtering, geo search, vector/semantic search, and a JavaScript InstantSearch UI.

Typesense targets developers who need a search backend that is simpler to operate than ElasticSearch and more affordable than Algolia, while still delivering fast, relevant results.

How it saves time or tokens

Typesense requires minimal configuration compared to ElasticSearch. There is no cluster management, shard allocation, or mapping complexity. You create a collection with a schema, index documents, and search. Typo tolerance, ranking, and stemming work without tuning.

How to use

1. Run Typesense with Docker:

docker run -d --name typesense \
  -p 8108:8108 \
  -v typesense-data:/data \
  typesense/typesense:latest \
  --data-dir /data \
  --api-key=your-api-key \
  --enable-cors

1. Create a collection and index documents via the REST API.

1. Search using the API or the InstantSearch.js UI library.

Example

# Create a collection
curl 'http://localhost:8108/collections' \
  -X POST \
  -H 'X-TYPESENSE-API-KEY: your-api-key' \
  -d '{
    "name": "tools",
    "fields": [
      {"name": "title", "type": "string"},
      {"name": "description", "type": "string"},
      {"name": "stars", "type": "int32"}
    ],
    "default_sorting_field": "stars"
  }'

# Search with typo tolerance
curl 'http://localhost:8108/collections/tools/documents/search?q=typsnse&query_by=title,description' \
  -H 'X-TYPESENSE-API-KEY: your-api-key'

Common pitfalls

• Typesense keeps the entire index in RAM for speed. Ensure your server has enough memory for your dataset size.
• The API key passed at startup is the admin key. Create scoped search-only keys for client-side use to prevent unauthorized writes.
• Typesense does not support multi-node clusters in the open-source edition. Typesense Cloud provides managed clustering.
