🚀 Getting started

Add Documents

import meilisearch

client = meilisearch.Client('http://127.0.0.1:7700', 'masterKey')

# An index is where the documents are stored.
index = client.index('movies')

documents = [
      { 'id': 1, 'title': 'Carol', 'genres': ['Romance', 'Drama'] },
      { 'id': 2, 'title': 'Wonder Woman', 'genres': ['Action', 'Adventure'] },
      { 'id': 3, 'title': 'Life of Pi', 'genres': ['Adventure', 'Drama'] },
      { 'id': 4, 'title': 'Mad Max: Fury Road', 'genres': ['Adventure', 'Science Fiction'] },
      { 'id': 5, 'title': 'Moana', 'genres': ['Fantasy', 'Action']},
      { 'id': 6, 'title': 'Philadelphia', 'genres': ['Drama'] },
]

# If the index 'movies' does not exist, Meilisearch creates it when you first add the documents.
index.add_documents(documents) # => { "uid": 0 }

With the task uid, you can check the status (enqueued, canceled, processing, succeeded or failed) of your documents addition using the task.

Basic Search

# Meilisearch is typo-tolerant:
index.search('caorl')

Output:

{
  "hits": [
    {
      "id": 1,
      "title": "Carol",
      "genre": ["Romance", "Drama"]
    }
  ],
  "offset": 0,
  "limit": 20,
  "processingTimeMs": 1,
  "query": "caorl"
}

Custom Search

All the supported options are described in the search parameters

index.search(
  'phil',
  {
    'attributesToHighlight': ['*'],
  }
)

JSON output:

{
  "hits": [
    {
      "id": 6,
      "title": "Philadelphia",
      "_formatted": {
        "id": 6,
        "title": "<em>Phil</em>adelphia",
        "genre": ["Drama"]
      }
    }
  ],
  "offset": 0,
  "limit": 20,
  "processingTimeMs": 0,
  "query": "phil"
}

Custom Search With Filters

If you want to enable filtering, you must add your attributes to the filterableAttributes index setting.

index.update_filterable_attributes([
  'id',
  'genres'
])

Custom Serializer for documents

If your documents contain fields that the Python JSON serializer does not know how to handle you can use your own custom serializer.

from datetime import datetime
from json import JSONEncoder
from uuid import uuid4


class CustomEncoder(JSONEncoder):
    def default(self, o):
        if isinstance(o, (UUID, datetime)):
            return str(o)

        # Let the base class default method raise the TypeError
        return super().default(o)


documents = [
    {"id": uuid4(), "title": "test 1", "when": datetime.now()},
    {"id": uuid4(), "title": "Test 2", "when": datetime.now()},
]
index.add_documents(documents, serializer=CustomEncoder)

You only need to perform this operation once.

Note that Meilisearch will rebuild your index whenever you update filterableAttributes. Depending on the size of your dataset, this might take time. You can track the process using the task.

Then, you can perform the search:

index.search(
  'wonder',
  {
    'filter': ['id > 1 AND genres = Action']
  }
)

{
  "hits": [
    {
      "id": 2,
      "title": "Wonder Woman",
      "genres": ["Action", "Adventure"]
    }
  ],
  "offset": 0,
  "limit": 20,
  "estimatedTotalHits": 1,
  "processingTimeMs": 0,
  "query": "wonder"
}
