The Application Framework Simple Search uses only framework-specific data, so it is simpler to use and supports all needed query operations. This search interface is also the recommended one to use.

The Application Framework JAXR-Based Search combines framework and JAXR-based data. The advantage of this search is that it can use the whole JAXR-based functionality to query the registry. The disadvantage is that in order to use it, the user must have considerable knowledge of JAXR.
