KinoSearch1::Search::QueryFilter - build a filter based on results of a query
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, );
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.
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.
