🏃‍♀️ Run MeiliSearch

There are many easy ways to download and run a MeiliSearch instance.

For example, if you use Docker:

$ docker pull getmeili/meilisearch:latest # Fetch the latest version of MeiliSearch image from Docker Hub
$ docker run -it --rm -p 7700:7700 getmeili/meilisearch:latest ./meilisearch --master-key=masterKey

NB: you can also download MeiliSearch from Homebrew or APT.

Import

Front End or ESmodule

import MeiliSearch from 'meilisearch'

const client = new MeiliSearch({
  host: 'http://127.0.0.1:7700',
  apiKey: 'masterKey',
})

HTML Import

<script src="https://cdn.jsdelivr.net/npm/meilisearch@latest/dist/bundles/meilisearch.browser.js"></script>
<script>
  const client = new MeiliSearch({
    host: 'http://127.0.0.1:7700',
    apiKey: 'masterKey',
  })
  client.listIndexes().then(res => {
    console.log({ res });
  })
</script>

Back-End CommonJs

const MeiliSearch = require('meilisearch')

const client = new MeiliSearch({
  host: 'http://127.0.0.1:7700',
  apiKey: 'masterKey',
})

🎬 Getting started

Here is a quickstart for a search request

const MeiliSearch = require('meilisearch')
// Or if you are on a front-end environment:
import MeiliSearch from 'meilisearch'
;(async () => {
  const client = new MeiliSearch({
    host: 'http://127.0.0.1:7700',
    apiKey: 'masterKey',
  })

  const index = await client.createIndex('books') // If your index does not exist
  // OR
  const index = client.getIndex('books') // If your index exists

  const documents = [
    { book_id: 123, title: 'Pride and Prejudice' },
    { book_id: 456, title: 'Le Petit Prince' },
    { book_id: 1, title: 'Alice In Wonderland' },
    { book_id: 1344, title: 'The Hobbit' },
    { book_id: 4, title: 'Harry Potter and the Half-Blood Prince' },
    { book_id: 42, title: "The Hitchhiker's Guide to the Galaxy" },
  ]

  let response = await index.addDocuments(documents)
  console.log(response) // => { "updateId": 0 }
})()

With the updateId, you can check the status (processed or failed) of your documents addition thanks to this method.

Search in index

// MeiliSearch is typo-tolerant:
const search = await index.search('harry pottre')
console.log(search)

Output:

{
  "hits": [
    {
      "book_id": 4,
      "title": "Harry Potter and the Half-Blood Prince"
    }
  ],
  "offset": 0,
  "limit": 20,
  "processingTimeMs": 1,
  "query": "harry pottre"
}

You can check out the API documentation.

Go checkout examples!

In this section, the examples contain the await keyword.

Indexes

Create an index

// Create an index
const index = await client.createIndex('books')
// Create an index and give the primary-key
const index = await client.createIndex('books', { primaryKey: 'book_id' })

List all indexes

const indexes = await client.listIndexes()

Get an index object

const index = client.getIndex('books')

Documents

Fetch documents

// Get one document
const document = await index.getDocument(123)

// Get documents by batch
const documents = await index.getDocuments({ offset: 4, limit: 20 })

Add documents

await index.addDocuments([{ book_id: 2, title: 'Madame Bovary' }])

Response:

{
  "updateId": 1
}

With this updateId you can track your operation update.

Delete documents

// Delete one document
await index.deleteDocument(2)
// Delete several documents
await index.deleteDocuments([1, 42])
// Delete all documents /!\
await index.deleteAllDocuments()

Update status

// Get one update
// Parameter: the updateId got after an asynchronous request (e.g. documents addition)
await index.getUpdateStatus(1)
// Get all update satus
await index.getAllUpdateStatus()

Search

Basic search

const search = await index.search('prince')

{
  "hits": [
    {
      "book_id": 456,
      "title": "Le Petit Prince"
    },
    {
      "book_id": 4,
      "title": "Harry Potter and the Half-Blood Prince"
    }
  ],
  "offset": 0,
  "limit": 20,
  "processingTimeMs": 13,
  "query": "prince"
}

Custom search

All the supported options are described in this documentation section.

await index.search('prince', { limit: 1, attributesToHighlight: '*' })

{
  "hits": [
    {
      "book_id": 456,
      "title": "Le Petit Prince",
      "_formatted": {
        "book_id": 456,
        "title": "Le Petit <em>Prince</em>"
      }
    }
  ],
  "offset": 0,
  "limit": 1,
  "processingTimeMs": 0,
  "query": "prince"
}

Placeholder Search

Placeholder search makes it possible to receive hits based on your parameters without having any query (q). To enable this behavior, instead of sending an empty string, the query should be null or undefined.

await index.search(null, {
  facetFilters: ['genre:fantasy'],
  facetsDistribution: ['genre']
})

{
  "hits": [
    {
      "genre": "fantasy",
      "id": 4,
      "title": "Harry Potter and the Half-Blood Prince",
      "comment": "The best book"
    },
    {
      "genre": "fantasy",
      "id": 42,
      "title": "The Hitchhiker's Guide to the Galaxy"
    }
  ],
  "offset": 0,
  "limit": 20,
  "nbHits": 2,
  "exhaustiveNbHits": false,
  "processingTimeMs": 0,
  "query": "",
  "facetsDistribution": { "genre": { "fantasy": 2, "romance": 0, "sci fi": 0, "adventure": 0 } },
  "exhaustiveFacetsCount": true
}
