# Create a simple search engine

Use the `search()` method to implement a simple search engine. This example uses the [Workers binding](https://developers.cloudflare.com/ai-search/api/search/workers-binding/), but can be adapted to use the [REST API](https://developers.cloudflare.com/ai-search/api/search/rest-api/) instead.

To replicate this example:

* Disable query rewriting so that the original user query is matched directly
* Configure your AI Search instance to have small chunk sizes (256 tokens is usually enough)

* [  JavaScript ](#tab-panel-4444)
* [  TypeScript ](#tab-panel-4445)

JavaScript

```

export default {

  async fetch(request, env) {

    const url = new URL(request.url);

    const userQuery = url.searchParams.get("query") ?? "What is Cloudflare?";


    const searchResult = await env.AI_SEARCH.get("my-instance").search({

      messages: [{ role: "user", content: userQuery }],

    });


    return Response.json({

      files: searchResult.chunks.map((chunk) => chunk.item.key),

    });

  },

};


```

TypeScript

```

export interface Env {

  AI_SEARCH: AiSearchNamespace;

}


export default {

  async fetch(request, env): Promise<Response> {

    const url = new URL(request.url);

    const userQuery = url.searchParams.get("query") ?? "What is Cloudflare?";


    const searchResult = await env.AI_SEARCH.get("my-instance").search({

      messages: [{ role: "user", content: userQuery }],

    });


    return Response.json({

      files: searchResult.chunks.map((chunk) => chunk.item.key),

    });

  },

} satisfies ExportedHandler<Env>;
