/**
* The data model for saved searches. Each users has his or her own set of
* saved searches, but inventory managers are allowed to "promote" their
* saved searches to GLOBAL status, which makes them available to all users
* under that installation of RHQ.
*
* There are two levels of pre-computed data within this structured. After
* the {@link SavedSearch} is created, the pattern will be translated into its
* JPQL equivalent and stored. If the {@link SavedSearch} is ever modified
* and saved, the JPQL will be re-computed.
*
* Periodically, the count-query version of the {@link SavedSearch} will be
* executed (using the stored JPQL), and the number of matching records will
* be stored. If this {@link SavedSearch} ever needs to be displayed on the
* user interface, it will by default retrieve this cached result count.
