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.
