Services of WQS-extension for Thingworx

There is a SearchRecords-service for PTC.Resource.WQS.SearchUtils Thing. With its help I want to find the project and the system, related to particular part (record in other words). But I can't understand the meaning of its input parameters. Should I enter the name of my part to SearchText-field or something else? And what exactly should I enter to ConfigThingName-field?

Does anyone know?
