NAME

6       KinoSearch1::Search::QueryFilter - build a filter based on results of a
7       query
8

SYNOPSIS

10           my $books_only_query  = KinoSearch1::Search::TermQuery->new(
11               term => KinoSearch1::Index::Term->new( 'category', 'books' );
12           );
13           my $filter = KinoSearch1::Search::QueryFilter->new(
14               query => $books_only_query;
15           );
16           my $hits = $searcher->search(
17               query  => $query_string,
18               filter => $filter,
19           );

DESCRIPTION

22       A QueryFilter spawns a result set that can be used to filter the
23       results of another query.  The effect is very similar to adding a
24       required clause to a BooleanQuery -- however, a QueryFilter caches its
25       results, so it is more efficient if you use it more than once.
26

METHODS

28   new
29           my $filter = KinoSearch1::Search::QueryFilter->new(
30               query => $query;
31           );
32
33       Constructor.  Takes one hash-style parameter, "query", which must be an
34       object belonging to a subclass of KinoSearch1::Search::Query.
