🚀 Getting Started

Add Documents

using System;
using System.Threading.Tasks;
using Meilisearch;

namespace GettingStarted
{
    class Program
    {
        public class Movie
        {
            public string Id { get; set; }
            public string Title { get; set; }
            public IEnumerable<string> Genres { get; set; }
        }

        static async Task Main(string[] args)
        {
            MeilisearchClient client = new MeilisearchClient("http://localhost:7700", "masterKey");

            // An index is where the documents are stored.
            var index = client.Index("movies");
            var documents = new Movie[] {
                new Movie { Id = "1", Title = "Carol", Genres = new string[] { "Romance", "Drama" }  },
                new Movie { Id = "2", Title = "Wonder Woman", Genres = new string[] { "Action", "Adventure" } },
                new Movie { Id = "3", Title = "Life of Pi", Genres = new string[] { "Adventure", "Drama" } },
                new Movie { Id = "4", Title = "Mad Max: Fury Road", Genres = new string[] { "Adventure", "Science Fiction"} },
                new Movie { Id = "5", Title = "Moana", Genres = new string[] { "Fantasy", "Action" } },
                new Movie { Id = "6", Title = "Philadelphia", Genres = new string[] { "Drama" } }
            };

            // If the index 'movies' does not exist, MeiliSearch creates it when you first add the documents.
            var update = await index.AddDocuments<Movie>(documents); // # => { "updateId": 0 }
        }
    }
}

With the updateId (via update.UpdateId), you can check the status (enqueued, processing, processed or failed) of your documents addition using the update endpoint.

Basic Search

# MeiliSearch is typo-tolerant:
SearchResult<Movie> movies = await index.Search<Movie>("philadalphia");
foreach(var prop in movies.Hits) {
    Console.WriteLine (prop.Title);
}

JSON Output:

{
    "hits": [
        {
            "id": 6,
            "title": "Philadelphia",
        }
    ],
    "offset": 0,
    "limit": 20,
    "processingTimeMs": 10,
    "query": "philadalphia"
}

Custom Search

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

SearchResult<Movie> movies = await index.Search<Movie>(
    "car",
    new SearchQuery
    {
        AttributesToHighlight = new string[] { "title" },
    }
);

foreach(var prop in movies.Hits) {
    Console.WriteLine (prop.Title);
}

JSON Output:

{
    "hits": [
        {
            "id": 1,
            "title": "Carol",
            "_formatted": {
                "id": 1,
                "title": "<em>Car</em>ol"
            }
        }
    ],
    "offset": 0,
    "limit": 20,
    "processingTimeMs": 10,
    "query": "car"
}

var indexes = await client.GetAllIndexes();

Get an Index object

var index = await client.GetIndex("movies");

Documents

Add or Update Documents

var updateStatus = await index.AddDocuments(new Movie[] { new Movie { Id = "1", Title = "Carol" } } );
var updateStatus = await index.UpdateDocuments(new Movie[] { new Movie { Id = "1", Title = "Carol" } } );

Update Status has a reference UpdateId to get the status of the action.

Get Documents

var documents = await index.GetDocuments<Movie>(new DocumentQuery { Limit = 1 });

Get Document by Id

var document = await index.GetDocument<Movie>("10");

Delete documents

var updateStatus = await index.DeleteOneDocument("11");

Delete in Batch

var updateStatus = await index.DeleteDocuments(new [] {"12","13","14"});

Delete all documents

var updateStatus = await indextoDelete.DeleteAllDocuments();

Update Status

Get Update Status By Id

UpdateStatus individualStatus = await index.GetUpdateStatus(1);

Get All Update Status

var status = await index.GetAllUpdateStatus();

Search

Basic Search

var movies = await this.index.Search<Movie>("prince");

Custom Search

var movies = await this.index.Search<Movie>("prince", new SearchQuery { Limit = 100 });

🧰 Use a Custom HTTP Client

You can replace the default client used in this package by the one you want.

For example:

var _httpClient = ClientFactory.Instance.CreateClient<MeilisearchClient>();
var client = new MeilisearchClient(_httpClient);

Where ClientFactory is declared like this.
