NAME

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

SYNOPSIS

     my $books_only_query  = KinoSearch::Search::TermQuery->new(
         term => KinoSearch::Index::Term->new( 'category', 'books' );
     );
     my $filter = KinoSearch::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 = KinoSearch::Search::QueryFilter->new(
         query => $query;
     );

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