SearchClient class

  • Reference
Package:
@azure/search-documents

Class used to perform operations against a search index, including querying documents in the index as well as adding, updating, and removing them.

Constructors

SearchClient<TModel>(string, string, KeyCredential | TokenCredential, SearchClientOptions)

Creates an instance of SearchClient.

Example usage:

const { SearchClient, AzureKeyCredential } = require("@azure/search-documents");

const client = new SearchClient(
  "<endpoint>",
  "<indexName>",
  new AzureKeyCredential("<Admin Key>")
);

Optionally, the type of the model can be used to enable strong typing and type hints:

type TModel = {
  keyName: string;
  field1?: string | null;
  field2?: { anotherField?: string | null } | null;
};

const client = new SearchClient<TModel>(
  ...
);

Properties

apiVersion

The API version to use when communicating with the service.
endpoint

indexName

The name of the index
serviceVersion

The service version to use when communicating with the service.

type TModel = {
  key: string;
  azure?: { sdk: string | null } | null;
};

const client = new SearchClient<TModel>(
  "endpoint.azure",
  "indexName",
  new AzureKeyCredential("key")
);

const searchFields: SearchFieldArray<TModel> = ["azure/sdk"];

const autocompleteResult = await client.autocomplete(
  "searchText",
  "suggesterName",
  { searchFields }
);
