Web Search on AWS Bedrock now supports domain filtering and user location!

Hi everyone, it's Shii-chan! Here is an update that gives you much more control over the search results that ground a model's answers.

AWS What's New aws.amazon.com

What was announced?

In AWS What's New, AWS announced two new controls for Web Search on AWS Bedrock. Both are configured directly on the web_search tool in your existing OpenAI Responses API request.

• Domain filtering: limit results to domains you choose, or exclude some
• User location: optionally pass location parameters so results fit a geography

Why it matters

A model's answer is built on its search results. Choosing which sites those come from helps when you want answers grounded only in trusted sources, or when certain domains must stay out.

What changes

• If you want answers based on trusted sites only, you can set allowed domains
• If there are sources you don't want, you can block them
• For location-dependent questions such as regional availability or local services, you can pass a location

Dive Deep

Details from the original announcement:

• Domain filtering uses the filters parameter
• allowed_domains takes up to 100 domains to limit results to trusted sources
• blocked_domains takes up to 100 domains to exclude sources
• Location is optional

Both are available in all AWS Regions where Web Search is supported:

• US East (N. Virginia)
• US East (Ohio)
• US West (Oregon)
• AWS GovCloud (US-West)

To get started, see the Web Search section in the AWS Bedrock User Guide. For pricing, see the AWS Bedrock pricing page.

Wrap-up

• Web Search on Bedrock gains domain filtering and user location
• filters accepts up to 100 allowed or 100 blocked domains
• Configure it on the web_search tool in the OpenAI Responses API request
• Available in the four Regions where Web Search is supported

If you build search-grounded apps on Bedrock and want to curate sources, this one is for you!
