Run MeiliSearch

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

For example, if you use Docker:

$ docker run -it --rm -p 7700:7700 getmeili/meilisearch:latest ./meilisearch --master-key=masterKey

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

🚀 Getting started

Add documents

import meilisearch

client = meilisearch.Client('http://127.0.0.1:7700', 'masterKey')
index = client.create_index('books') # If your index does not exist
index = client.get_index('books')    # If you already created your index

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' }
]

index.add_documents(documents) # => { "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:
index.search('harry pottre')

Output:

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