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.

💡 Getting Started

Install the library with the .NET CLI:

dotnet add package Algolia.Search

or with the Nuget Package Manager Console:

Install-Package Algolia.Search

In 30 seconds, this quick start tutorial will show you how to index and search objects.

Initialize the cient

To start, you need to initialize the client. To do this, you need your Application ID and API Key. You can find both on your Algolia account.

SearchClient client = new SearchClient("YourApplicationID", "YourAPIKey");
SearchIndex index = client.InitIndex("your_index_name");

Push data

Without any prior configuration, you can start indexing contacts in the contacts index using the following code:

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

SearchIndex index = client.InitIndex("contacts");

index.SaveObject(new Contact
    ObjectID = "ID1",
    Name = "Jimmie",
    Age = 30


You can now search for contacts by firstname, lastname, company, etc. (even with typos):

// Synchronous
index.Search<Contact>(new Query { "jimmie" });

// Asynchronous
await index.SearchAsync<Contact>(new Query { "jimmie" });
