🚀 Getting Started

Add Documents <!-- omit in toc -->

import 'package:meilisearch/meilisearch.dart';

void main() async {
  var client = MeiliSearchClient('http://127.0.0.1:7700', 'masterKey');

  // An index is where the documents are stored.
  var index = client.index('movies');

  const 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.
  var task = await index.addDocuments(documents); // => { "uid": 0 }
}

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

Basic Search <!-- omit in toc -->

// Meilisearch is typo-tolerant:
var result = await index.search('carlo');

print(result.hits);

JSON Output:

[
  {
    "id": 1,
    "title": "Carol",
    "genres": ["Romance", "Drama"]
  }
]

Custom Search <!-- omit in toc -->

All the supported options are described in the search parameters section of the documentation.

var result = await index.search(
  'carol',
  attributesToHighlight: ['title'],
);

JSON output:

{
    "hits": [
        {
            "id": 1,
            "title": "Carol",
            "_formatted": {
                "id": 1,
                "title": "<em>Carol</em>"
            }
        }
    ],
    "offset": 0,
    "limit": 20,
    "processingTimeMs": 0,
    "query": "carol"
}

Custom Search With Filters <!-- omit in toc -->

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

await index.updateFilterableAttributes(['id', 'genres']);

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 status.

Then, you can perform the search:

await 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"
}
