GRID QUERIES

摘要

Aspects of the subject matter described herein relate to grid queries. In aspects, a client sends search criteria that represent two or more dimensions to a service. The service obtains results that satisfy the search criteria and performs intersection operations to populate a data grid. The data grid is then returned to the client for output on an output device of the client. The client may provide a user interface that allows quick updating of the search criteria to obtain a new data grid.
