NAME
       Plucene::Search::Filter - A search filter base class

DESCRIPTION
       This doesn't seem to be being used just yet. But here is some info on filters:

       Filtering means imposing additional restriction on the hit list to eliminate hits that
       otherwise would be included in the search results.

       There are two ways to filter hits:

       * Search Query - in this approach, provide your custom filter object to the when you call
       the search() method. This filter will be called exactly once to evaluate every document
       that resulted in non zero score.
       * Selective Collection - in this approach you perform the regular search and when you get
       back the hit list, collect only those that matches your filtering criteria. In this
       approach, your filter is called only for hits that returned by the search method which may
       be only a subset of the non zero matches (useful when evaluating your search filter is
       expensive).

METHODS
       bits

       This must be defined in a subclass
