Amazon Bedrock's Web Search tool incorporated domain filtering, allowing users to restrict search results to specified trusted or excluded domains within OpenAI Responses API requests. This helps tailor model grounding for scenarios needing trusted sources or excluding others.
User location parameters were also introduced, improving the relevance of search results for location-dependent queries by specifying geographic context. These features have been rolled out in multiple AWS Regions including US commercial and GovCloud environments, enhancing control over the information grounding Amazon Bedrock models use.
