The various client libraries define classes like Index, Field, and Document, as well as operations like Indexes.Create and Documents.Search on the SearchServiceClient and SearchIndexClient classes.
Example:
The sample application we'll be exploring creates a new index named "hotels", populates it with a few documents, then executes some search queries. Here is the main program, showing the overall flow:
/ This sample shows how to delete, create, upload documents and query an index static void Main(string[] args)
{
IConfigurationBuilder builder = new ConfigurationBuilder().AddJsonFile("appsettings.json"); IConfigurationRoot configuration = builder.Build(); SearchServiceClient serviceClient = CreateSearchServiceClient(configuration); Console.WriteLine("{0}", "Deleting index...\n"); DeleteHotelsIndexIfExists(serviceClient); Console.WriteLine("{0}", "Creating index...\n"); CreateHotelsIndex(serviceClient); ISearchIndexClient indexClient = serviceClient.Indexes.GetClient("hotels"); References:
