Filtering the Results of Searches
Your application will often need to process only a subset of the data in the database tables. In these cases, you can create a Hibernate filter to eliminate the unwanted data. Filters provide a way for your application to limit the results of a query to data that passes the filter’s criteria. Filters are not a new concept — you can achieve much the same effect using SQL database views or, well, named queries — but Hibernate offers a centralized management system for them.
