KinoSearch1::Search::QUserFContributed PerlKinoSearch1::Search::QueryFilter(3)

NAME
       KinoSearch1::Search::QueryFilter - build a filter based on results of a
       query

SYNOPSIS
	   my $books_only_query	 = KinoSearch1::Search::TermQuery->new(
	       term => KinoSearch1::Index::Term->new( 'category', 'books' );
	   );
	   my $filter = KinoSearch1::Search::QueryFilter->new(
	       query => $books_only_query;
	   );
	   my $hits = $searcher->search(
	       query  => $query_string,
	       filter => $filter,
	   );

DESCRIPTION
       A QueryFilter spawns a result set that can be used to filter the
       results of another query.  The effect is very similar to adding a
       required clause to a BooleanQuery -- however, a QueryFilter caches its
       results, so it is more efficient if you use it more than once.

METHODS
   new
	   my $filter = KinoSearch1::Search::QueryFilter->new(
	       query => $query;
	   );

       Constructor.  Takes one hash-style parameter, "query", which must be an
       object belonging to a subclass of KinoSearch1::Search::Query.
