dotnet add package Algolia.Search

With the Nuget Package Manager Console:

1
Install-Package Algolia.Search

With Nuget.org

Download the package on Nuget.org.

Supported platforms

The API client follows .NET Standard thus it’s compatible with:

  • .NET Standard 1.3 to .NET Standard 2.1,
  • .NET Core 1.0 to .NET Core 3.0,
  • .NET Framework 4.5 to .NET Framework 4.7.1

Source on GitHub

All our API clients are open source and available on Github.

Language-specific notes

Migration note from v5.x to v6.x

In January 2019, we released v6 of our .NET client. If you are using version 5.x of the client, read the migration guide to version 6.x. Version 5.x will no longer be under active development.

Note: If you’re using ASP.NET, checkout the following tutorial.

Philosophy

POCO, Types and Json.NET

The API client is using Json.NET as serializer.

The Client is meant to be used with POCOs and Types to improve type safety and developer experience. You can directly index your POCOs if they follow the .NET naming convention for class and properties:

  • PascalCase for property names
  • PascalCase for class name

public class Contact
{
  public string ObjectID { get; set; }
  public string Name { get; set; }
  public int Age { get; set; }
}

SearchClient client = new SearchClient("YourApplicationID", "YourAdminAPIKey");
SearchIndex index = client.InitIndex("contact");

IEnumerable<Contact> contacts; // Fetch from DB or a Json file
index.SaveObjects(contacts);

// Retrieve one typed Contact
Contact contact = index.GetObject<Contact>("myId");

// Search one typed Contact
var result = index.Search<Contact>(new Query("contact"));

If you can’t follow the convention, you can still override the naming strategy with the following attribute [JsonProperty(PropertyName = "propertyName")]

However, it’s still possible to use JObject to add and retrieve records.

    using (StreamReader re = File.OpenText("contacts.json"))
    using (JsonTextReader reader = new JsonTextReader(re))
    {
        JArray batch = JArray.Load(reader);
        index.SaveObjects(batch).Wait();
    }

    // Retrieve one JObject Contact
    JObject contact = index.GetObject<JObject>("myId");

Algolia objects such as Rule, Synonym, Settings, etc., are now typed. You can enjoy the completion of your favorite IDE while developing with the library.

Example with the Settings class:

IndexSettings settings = new IndexSettings
{
    SearchableAttributes = new List<string> {"attribute1", "attribute2"},
    AttributesForFaceting = new List<string> {"filterOnly(attribute2)"},
    UnretrievableAttributes = new List<string> {"attribute1", "attribute2"},
    AttributesToRetrieve = new List<string> {"attribute3", "attribute4"}
    // etc.
};

index.SetSettings(settings);

Asynchronous & Synchronous Methods

The API client provides both Async and Sync methods for every API endpoint. Asynchronous methods are suffixed with the Async keyword. You can use any of them depending on your needs.

// Synchronous
Contact res = index.GetObject<Contact>("myId");

// Asynchronous
Contact res = await index.GetObjectAsync<Contact>("myId");

HttpClient Injection

The API client is using the built-in HttpClient of the .NET Framework.

The HttpClient is wrapped in an interface: IHttpRequester. If you wish to use another HttpClient, you can inject it through the constructor while instantiating a SearchClient, AnalyticsClient, and InsightsClient.

Example:

1
2
3
4
5
6
IHttpRequester myCustomHttpClient = new MyCustomHttpClient();

SearchClient client = new SearchClient(
    new SearchConfig("YourApplicationID", "YourAdminAPIKey"),
    myCustomHttpClient
);

Multithreading

The client is designed to be thread-safe. You can use SearchClient, AnalyticsClient, and InsightsClient in a multithreaded environment.

Cross-Platform

As the API client is following .NET Standard, it can be used on Windows, Linux, or MacOS. The library is continuously tested in all three environments. If you want more information about .NET Standard, you can visit the official page.
