/**
* @file
*
* Provides a way for setools to make queries about conditional
* booleans within a policy. The caller obtains a query object, fills
* in its parameters, and then runs the query; it obtains a vector of
* results. Searches are conjunctive -- all fields of the search
* query must match for a datum to be added to the results query.
