§🚀 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>,
}


fn main() { block_on(async move {
    // Create a client (without sending any request so that can't fail)
    let client = Client::new(MEILISEARCH_URL, Some(MEILISEARCH_API_KEY));

    // 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"
}
