# App Search Connector
<admonition title="Deprecation Notice">
  App Search connector for Search UI is deprecated and will no longer be supported. Please migrate to [Elasticsearch Connector](https://www.elastic.co/elastic/docs-builder/docs/3016/reference/search-ui/api-connectors-elasticsearch) for continued support.
</admonition>

This Connector is used to connect Search UI to Elastic’s [App Search](https://www.elastic.co/cloud/app-search-service) API.

## Usage

```shell
npm install --save @elastic/search-ui-app-search-connector
```

```js
import AppSearchAPIConnector from "@elastic/search-ui-app-search-connector";

const connector = new AppSearchAPIConnector({
  searchKey: "search-371auk61r2bwqtdzocdgutmg",
  engineName: "search-ui-examples",
  endpointBase: "http://127.0.0.1:3002"
});
```


### Additional options

Additional options will be passed through to the underlying [APIclient](https://github.com/elastic/app-search-javascript). Any valid parameter of the client can be used.
```js
const connector = new AppSearchAPIConnector({
  searchKey: "search-371auk61r2bwqtdzocdgutmg",
  engineName: "search-ui-examples",
  endpointBase: "http://127.0.0.1:3002",
  cacheResponses: false
});
