Features

Typo Tolerance: Handles typographical errors elegantly, out-of-the-box.
Simple and Delightful: Simple to set-up, integrate with, operate and scale.
⚡ Blazing Fast: Built in C++. Meticulously architected from the ground-up for low-latency (<50ms) instant searches.
Tunable Ranking: Easy to tailor your search results to perfection.
Sorting: Dynamically sort results based on a particular field at query time (helpful for features like "Sort by Price (asc)").
Faceting & Filtering: Drill down and refine results.
Grouping & Distinct: Group similar results together to show more variety.
Federated Search: Search across multiple collections (indices) in a single HTTP request.
Geo Search: Search and sort by results around a latitude/longitude or within a bounding box.
Vector Search: Index embeddings from your machine learning models in Typesense and do a nearest-neighbor search. Can be used to build similarity search, semantic search, visual search, recommendations, etc.
Semantic / Hybrid Search: Automatically generate embeddings from within Typesense using built-in models like S-BERT, E-5, etc or use OpenAI, PaLM API, etc, for both queries and indexed data. This allows you to send JSON data into Typesense and build an out-of-the-box semantic search + keyword search experience.
Conversational Search (Built-in RAG): Send questions to Typesense and have the response be a fully-formed sentence, based on the data you've indexed in Typesense. Think ChatGPT, but over your own data.
Image Search: Search through images using text descriptions of their contents, or perform similarity searches, using the CLIP model.
Voice Search: Capture and send query via voice recordings - Typesense will transcribe (via Whisper model) and provide search results.
Scoped API Keys: Generate API keys that only allow access to certain records, for multi-tenant applications.
JOINs: Connect one or more collections via common reference fields and join them during query time. This allows you to model SQL-like relationships elegantly.
Synonyms: Define words as equivalents of each other, so searching for a word will also return results for the synonyms defined.
Curation & Merchandizing: 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.
Seamless Version Upgrades: As new versions of Typesense come out, upgrading is as simple as swapping out the binary and restarting Typesense.
No Runtime Dependencies: Typesense is a single binary that you can run locally or in production with a single command.

Install

Option 1: You can download the binary packages that we publish for Linux (x86_64 & arm64) and Mac (x86_64).

Option 2: You can also run Typesense from our official Docker image.

Option 3: Spin up a managed cluster with Typesense Cloud:

Quick Start

Here's a quick example showcasing how you can create a collection, index a document and search it on Typesense.

Let's begin by starting the Typesense server via Docker:

docker run -p 8108:8108 -v/tmp/data:/data typesense/typesense:26.0 --data-dir /data --api-key=Hu52dwsas2AdxdE

We have API Clients in a couple of languages, but let's use the Python client for this example.

Install the Python client for Typesense:

pip install typesense

We can now initialize the client and create a companies collection:

import typesense

client = typesense.Client({
  'api_key': 'Hu52dwsas2AdxdE',
  'nodes': [{
    'host': 'localhost',
    'port': '8108',
    'protocol': 'http'
  }],
  'connection_timeout_seconds': 2
})

create_response = client.collections.create({
  "name": "companies",
  "fields": [
    {"name": "company_name", "type": "string" },
    {"name": "num_employees", "type": "int32" },
    {"name": "country", "type": "string", "facet": True }
  ],
  "default_sorting_field": "num_employees"
})

Now, let's add a document to the collection we just created:

document = {
 "id": "124",
 "company_name": "Stark Industries",
 "num_employees": 5215,
 "country": "USA"
}

client.collections['companies'].documents.create(document)

Finally, let's search for the document we just indexed:

search_parameters = {
  'q'         : 'stork',
  'query_by'  : 'company_name',
  'filter_by' : 'num_employees:>100',
  'sort_by'   : 'num_employees:desc'
}

client.collections['companies'].documents.search(search_parameters)

Did you notice the typo in the query text? No big deal. Typesense handles typographic errors out-of-the-box!

Step-by-step Walk-through

A step-by-step walk-through is available on our website here.

This will guide you through the process of starting up a Typesense server, indexing data in it and querying the data set.

API Documentation

Here's our official API documentation, available on our website: https://typesense.org/api.

If you notice any issues with the documentation or walk-through, please let us know or send us a PR here: https://github.com/typesense/typesense-website.

API Clients

While you can definitely use CURL to interact with Typesense Server directly, we offer official API clients to simplify using Typesense from your language of choice. The API Clients come built-in with a smart retry strategy to ensure that API calls made via them are resilient, especially in an HA setup.

If we don't offer an API client in your language, you can still use any popular HTTP client library to access Typesense's APIs directly.

Here are some community-contributed clients and integrations:

We welcome community contributions to add more official client libraries and integrations. Please reach out to us at [email protected] or open an issue on GitHub to collaborate with us on the architecture. 🙏

Framework Integrations

We also have the following framework integrations:

Laravel
Firebase
Gatsby
WordPress
WooCommerce
Symfony
InstantSearch
DocSearch
Docusaurus
ToolJet
Plone CMS
Craft CMS
SEAL provides integrations of Typesense in Laravel, Symfony, Spiral, Yii and Laminas Mezzio PHP Framework

Postman Collection

We have a community-maintained Postman Collection here: https://github.com/typesense/postman.

Postman is an app that let's you perform HTTP requests by pointing and clicking, instead of having to type them out in the terminal. The Postman Collection above gives you template requests that you can import into Postman, to quickly make API calls to Typesense.

Search UI Components

You can use our InstantSearch.js adapter to quickly build powerful search experiences, complete with filtering, sorting, pagination and more.

Here's how: https://typesense.org/docs/guide/search-ui-components.html

FAQ

How does this differ from Elasticsearch?

Elasticsearch is a large piece of software, that takes non-trivial amount of effort to setup, administer, scale and fine-tune. It offers you a few thousand configuration parameters to get to your ideal configuration. So it's better suited for large teams who have the bandwidth to get it production-ready, regularly monitor it and scale it, especially when they have a need to store billions of documents and petabytes of data (eg: logs).

Typesense is built specifically for decreasing the "time to market" for a delightful search experience. It's a light-weight yet powerful & scaleable alternative that focuses on Developer Happiness and Experience with a clean well-documented API, clear semantics and smart defaults so it just works well out-of-the-box, without you having to turn many knobs.

Elasticsearch also runs on the JVM, which by itself can be quite an effort to tune to run optimally. Typesense, on the other hand, is a single light-weight self-contained native binary, so it's simple to setup and operate.

See a side-by-side feature comparison here.

How does this differ from Algolia?

Algolia is a proprietary, hosted, search-as-a-service product that works well, when cost is not an issue. From our experience, fast growing sites and apps quickly run into search & indexing limits, accompanied by expensive plan upgrades as they scale.

Typesense on the other hand is an open-source product that you can run on your own infrastructure or use our managed SaaS offering - Typesense Cloud. The open source version is free to use (besides of course your own infra costs). With Typesense Cloud we don't charge by records or search operations. Instead, you get a dedicated cluster and you can throw as much data and traffic at it as it can handle. You only pay a fixed hourly cost & bandwidth charges for it, depending on the configuration your choose, similar to most modern cloud platforms.

From a product perspective, Typesense is closer in spirit to Algolia than Elasticsearch. However, we've addressed some important limitations with Algolia:

Algolia requires separate indices for each sort order, which counts towards your plan limits. Most of the index settings like fields to search, fields to facet, fields to group by, ranking settings, etc are defined upfront when the index is created vs being able to set them on the fly at query time.

With Typesense, these settings can be configured at search time via query parameters which makes it very flexible and unlocks new use cases. Typesense is also able to give you sorted results with a single index, vs having to create multiple. This helps reduce memory consumption.

Algolia offers the following features that Typesense does not have currently: personalization & server-based search analytics. For analytics, you can still instrument your search on the client-side and send search metrics to your web analytics tool of choice.

We intend to bridge this gap in Typesense, but in the meantime, please let us know if any of these are a show stopper for your use case by creating a feature request in our issue tracker.

See a side-by-side feature comparison here.

Speed is great, but what about the memory footprint?

A fresh Typesense server will consume about 30 MB of memory. As you start indexing documents, the memory use will increase correspondingly. How much it increases depends on the number and type of fields you index.

We've strived to keep the in-memory data structures lean. To give you a rough idea: when 1 million Hacker News titles are indexed along with their points, Typesense consumes 165 MB of memory. The same size of that data on disk in JSON format is 88 MB. If you have any numbers from your own datasets that we can add to this section, please send us a PR!

Why the GPL license?

From our experience companies are generally concerned when libraries they use are GPL licensed, since library code is directly integrated into their code and will lead to derivative work and trigger GPL compliance. However, Typesense Server is server software and we expect users to typically run it as a separate daemon, and not integrate it with their own code. GPL covers and allows for this use case generously (eg: Linux is GPL licensed). Now, AGPL is what makes server software accessed over a network result in derivative work and not GPL. And for that reason we’ve opted to not use AGPL for Typesense.

Now, if someone makes modifications to Typesense server, GPL actually allows you to still keep the modifications to yourself as long as you don't distribute the modified code. So a company can for example modify Typesense server and run the modified code internally and still not have to open source their modifications, as long as they make the modified code available to everyone who has access to the modified software.

Now, if someone makes modifications to Typesense server and distributes the modifications, that's where GPL kicks in. Given that we’ve published our work to the community, we'd like for others' modifications to also be made open to the community in the spirit of open source. We use GPL for this purpose. Other licenses would allow our open source work to be modified, made closed source and distributed, which we want to avoid with Typesense for the project’s long term sustainability.

Here's more background on why GPL, as described by Discourse: https://meta.discourse.org/t/why-gnu-license/2531. Many of the points mentioned there resonate with us.

Now, all of the above only apply to Typesense Server. Our client libraries are indeed meant to be integrated into our users’ code and so they use Apache license.

So in summary, AGPL is what is usually problematic for server software and we’ve opted not to use it. We believe GPL for Typesense Server captures the essence of what we want for this open source project. GPL has a long history of successfully being used by popular open source projects. Our libraries are still Apache licensed.

Typesense requires the following dependencies:

C++11 compatible compiler (GCC >= 4.9.0, Apple Clang >= 8.0, Clang >= 3.9.0)
Snappy
zlib
OpenSSL (>=1.0.2)
curl
ICU

Please refer to the CI build steps for the latest set of dependencies.

Once you've installed them, run the following from the root of the repo:

bazel build //:typesense-server

The first build will take some time since other third-party libraries are pulled and built as part of the build process.

	protected function filters(Builder $builder): string
	{
	return collect($builder->wheres)
	->map([
	$this,
	'parseFilters',
	])
	->values()
	->implode(' && ');
	}

	$this->typesense->importDocuments($collection, $models->map(fn ($m) => $m->toSearchableArray())
	->toArray());
