The ATG Control Center includes a number of UI components that you can use to create queries against repositories. For example, the People and Organizations > Profile Repository window displays an expression editor you can use to compose queries like this against the Profile Repository:
List Items of type User whose Gender is female
Note that the ATG Control Center limits the number of items that can be returned by such queries. This limit is configurable and is set in the maxQueryCount property of /atg/devtools/RepositoryAgent. The default value is 1000.
