We are excited to announce two new features for Amazon CloudSearch: support for custom tokenization dictionaries for Japanese and integration with Amazon CloudTrail. These new features are available immediately for all new and current CloudSearch domains based on the 2013-01-01 API version.

You can now control how Amazon CloudSearch tokenizes Japanese by adding a custom Japanese tokenization dictionary to the analysis scheme that you use for fields that contain Japanese. Configuring a custom tokenization dictionary can improve search result accuracy by facilitating indexing and retrieval of domain-specific phrases. To learn more about using custom dictionaries, see Customizing Japanese Tokenization in the Amazon CloudSearch Developer Guide.

You can now use Amazon CloudTrail to get a history of Amazon CloudSearch API calls and related events for your account. Amazon CloudTrail is a web service that records your account's API calls and delivers the resulting log files to your Amazon S3 bucket. You can also use CloudTrail to track changes that were made to your AWS resources. For example, you can use the API call history to perform a security analysis or troubleshoot operational issues. CloudTrail also makes it easier for you to demonstrate compliance with internal policies or regulatory standards. For more information, see the “Security at Scale: Logging in AWS” whitepaper.

You can turn on CloudTrail logging from the AWS Management Console in only two clicks. There is no additional charge for CloudTrail, but standard rates for Amazon S3 and Amazon SNS usage apply. Refer to Amazon S3 Amazon SNS pricing pages for details. To learn more about CloudTrail, visit the CloudTrail detail page.

Amazon CloudSearch is a fully-managed service that makes it easy to set up, manage, and scale a search solution for your website or application.

Please share your thoughts on these and any additional features you'd like to see in the CloudSearch forum. We really appreciate customer feedback, and we use it to help us prioritize upcoming features.
