Crate meilisearch_sdk

🚀 Getting started

Add Documents

use meilisearch_sdk::client::*;
use serde::{Serialize, Deserialize};
use futures::executor::block_on;

#[derive(Serialize, Deserialize, Debug)]
struct Movie {
    id: usize,
    title: String,
    genres: Vec<String>,
}


#[tokio::main(flavor = "current_thread")]
async fn main() {
    // Create a client (without sending any request so that can't fail)
    let client = Client::new(MEILISEARCH_URL, Some(MEILISEARCH_API_KEY)).unwrap();

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

    // Add some movies in the index. If the index 'movies' does not exist, Meilisearch creates it when you first add the documents.
    movies.add_documents(&[
        Movie { id: 1, title: String::from("Carol"), genres: vec!["Romance".to_string(), "Drama".to_string()] },
        Movie { id: 2, title: String::from("Wonder Woman"), genres: vec!["Action".to_string(), "Adventure".to_string()] },
        Movie { id: 3, title: String::from("Life of Pi"), genres: vec!["Adventure".to_string(), "Drama".to_string()] },
        Movie { id: 4, title: String::from("Mad Max"), genres: vec!["Adventure".to_string(), "Science Fiction".to_string()] },
        Movie { id: 5, title: String::from("Moana"), genres: vec!["Fantasy".to_string(), "Action".to_string()] },
        Movie { id: 6, title: String::from("Philadelphia"), genres: vec!["Drama".to_string()] },
    ], Some("id")).await.unwrap();
}

With the 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:
println!("{:?}", client.index("movies_2").search().with_query("caorl").execute::<Movie>().await.unwrap().hits);

Output:

[Movie { id: 1, title: String::from("Carol"), genres: vec!["Romance", "Drama"] }]

Json output:

{
  "hits": [{
    "id": 1,
    "title": "Carol",
    "genres": ["Romance", "Drama"]
  }],
  "offset": 0,
  "limit": 10,
  "processingTimeMs": 1,
  "query": "caorl"
}

Custom Search

let search_result = client.index("movies_3")
  .search()
  .with_query("phil")
  .with_attributes_to_highlight(Selectors::Some(&["*"]))
  .execute::<Movie>()
  .await
  .unwrap();
println!("{:?}", search_result.hits);

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.

let filterable_attributes = [
    "id",
    "genres",
];
client.index("movies_4").set_filterable_attributes(&filterable_attributes).await.unwrap();

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 tasks.

Then, you can perform the search:

let search_result = client.index("movies_5")
  .search()
  .with_query("wonder")
  .with_filter("id > 1 AND genres = Action")
  .execute::<Movie>()
  .await
  .unwrap();
println!("{:?}", search_result.hits);

Json output:

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

Customize the HttpClient

By default, the SDK uses reqwest to make http calls. The SDK lets you customize the http client by implementing the HttpClient trait yourself and initializing the Client with the new_with_client method. You may be interested by the futures-unsend feature which lets you specify a non-Send http client.

Wasm support

The SDK supports wasm through reqwest. You’ll need to enable the futures-unsend feature while importing it, though.
