🚀 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 string Genre {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 = await client.Index("movies");
            var documents = new Movie[] {
                new Movie { id = "1", Title = "Carol", Genre = ['Romance', 'Drama']  },
                new Movie { Id = "2", Title = "Wonder Woman", Genre = ['Action', 'Adventure']  },
                new Movie { Id = "3", Title = "Life of Pi", Genre = ['Adventure', 'Drama'] },
                new Movie { Id = "4", Title = "Mad Max: Fury Road", Genre = ['Adventure', 'Science Fiction'] },
                new Movie { Id = "5", Title = "Moana", Genre = ['Fantasy', 'Action']},
                new Movie { Id = "6", Title = "Philadelphia", Genre = ['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>(
    new SearchQuery
        AttributesToHighlight = new string[] { "title" },
foreach(var prop in movies.Hits) {
    Console.WriteLine (movies.Title);

JSON Output:

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