<p align="center">⚡ Lightning Fast, Ultra Relevant, and Typo-Tolerant Search Engine 🔍</p>
|
||
|
||
**MeiliSearch** is a powerful, fast, open-source, easy to use and deploy search engine. Both searching and indexing are highly customizable. Features such as typo-tolerance, filters, and synonyms are provided out-of-the-box.
|
||
For more information about features go to [our documentation](https://docs.meilisearch.com/).

|
||
|
||
## Get started
|
||
|
||
### Deploy the Server
|
||
|
||
#### Run it using Docker
|
||
|
||
```bash
|
||
docker run -p 7700:7700 -v $(pwd)/data.ms:/data.ms getmeili/meilisearch
|
||
```
|
||
|
||
#### Installing with Homebrew
|
||
|
||
```bash
|
||
brew update && brew install meilisearch
|
||
meilisearch
|
||
```
|
||
|
||
#### Installing with APT
|
||
|
||
```bash
|
||
echo "deb [trusted=yes] https://apt.fury.io/meilisearch/ /" > /etc/apt/sources.list.d/fury.list
|
||
apt update && apt install meilisearch-http
|
||
meilisearch
|
||
```
|
||
|
||
#### Download the binary
|
||
|
||
```bash
|
||
curl -L https://install.meilisearch.com | sh
|
||
./meilisearch
|
||
```
|
||
|
||
#### Compile and run it from sources
|
||
|
||
If you have the Rust toolchain already installed on your local system, clone the repository and change it to your working directory.
|
||
|
||
```bash
|
||
git clone https://github.com/meilisearch/MeiliSearch.git
|
||
cd MeiliSearch
|
||
```
|
||
|
||
In the cloned repository, compile MeiliSearch.
|
||
|
||
```bash
|
||
cargo run --release
|
||
```
|
||
|
||
### Create an Index and Upload Some Documents
|
||
|
||
Let's create an index! If you need a sample dataset, use [this movie database](https://www.notion.so/meilisearch/A-movies-dataset-to-test-Meili-1cbf7c9cfa4247249c40edfa22d7ca87#b5ae399b81834705ba5420ac70358a65). You can also find it in the `datasets/` directory.
|
||
|
||
```bash
|
||
curl -L 'https://bit.ly/2PAcw9l' -o movies.json
|
||
```
|
||
|
||
MeiliSearch can serve multiple indexes, with different kinds of documents.
|
||
It is required to create an index before sending documents to it.
|
||
|
||
```bash
|
||
curl -i -X POST 'http://127.0.0.1:7700/indexes' --data '{ "name": "Movies", "uid": "movies" }'
|
||
```
|
||
|
||
Now that the server knows about your brand new index, you're ready to send it some data.
|
||
|
||
```bash
|
||
curl -i -X POST 'http://127.0.0.1:7700/indexes/movies/documents' \
|
||
--header 'content-type: application/json' \
|
||
--data-binary @movies.json
|
||
```
|
||
|
||
### Search for Documents
|
||
|
||
#### In command line
|
||
|
||
The search engine is now aware of your documents and can serve those via an HTTP server.
|
||
|
||
The [`jq` command-line tool](https://stedolan.github.io/jq/) can greatly help you read the server responses.
|
||
|
||
```bash
|
||
curl 'http://127.0.0.1:7700/indexes/movies/search?q=botman+robin&limit=2' | jq
|
||
```
|
||
|
||
```json
|
||
{
|
||
"hits": [
|
||
{
|
||
"id": "415",
|
||
"title": "Batman & Robin",
|
||
"poster": "https://image.tmdb.org/t/p/w1280/79AYCcxw3kSKbhGpx1LiqaCAbwo.jpg",
|
||
"overview": "Along with crime-fighting partner Robin and new recruit Batgirl...",
|
||
"release_date": "1997-06-20",
|
||
},
|
||
{

|
||

|
||
"poster": "https://image.tmdb.org/t/p/w1280/GW3IyMW5Xgl0cgCN8wu96IlNpD.jpg",
|
||
"overview": "Adam West and Burt Ward returns to their iconic roles of Batman and Robin...",
|
||
"release_date": "2016-10-08",
|
||
}
|
||
],
|
||
"offset": 0,
|
||
"limit": 2,
|
||
"processingTimeMs": 1,
|
||
"query": "botman robin"
|
||
}
|
||
```
|
||
|
||
#### Use the Web Interface
|
||
|
||
We also deliver an **out-of-the-box web interface** in which you can test MeiliSearch interactively.
|
||
|
||
You can access the web interface in your web browser at the root of the server. The default URL is [http://127.0.0.1:7700](http://127.0.0.1:7700). All you need to do is open your web browser and enter MeiliSearch’s address to visit it. This will lead you to a web page with a search bar that will allow you to search in the selected index.

### Documentation
|
||
|
||
Now that your MeiliSearch server is up and running, you can learn more about how to tune your search engine in [the documentation](https://docs.meilisearch.com).
|
||
|
||
### Technical features

|
||
- Searches for [concatenated](https://github.com/meilisearch/MeiliSearch/pull/164) and [splitted query words](https://github.com/meilisearch/MeiliSearch/pull/232) to improve the search quality.
|
||

|
||
## Performances
|
||
|
||
When processing a dataset composed of 5M books, each with their own titles and authors, MeiliSearch is able to carry out more than 553 req/sec with an average response time of 21 ms on an Intel i7-7700 (8) @ 4.2GHz.
|
||
|
||
Requests are made using [wrk](https://github.com/wg/wrk) and scripted to simulate real users' queries.
|
||
|
||

||

|
||
```
|
||
|
||
We also indexed a dataset containing about _12 millions_ cities names in _24 minutes_ on a _8 cores_, _64 GB of RAM_, and a _300 GB NMVe_ SSD machine.<br/>
|
||
The size of the resulting database reached _16 GB_ and search results were presented between _30 ms_ and _4 seconds_ for short prefix queries.

### Analytic Events
|
||
|
||
Once a day, events are being sent to our Amplitude instance so we can know how many people are using MeiliSearch.<br/>
|
||
Only information about the platform on which the server runs is stored. No other information is being sent.<br/>
|
||
If this doesn't suit you, you can disable these analytics by using the `MEILI_NO_ANALYTICS` env variable.
