KinoSearch1::Search::BUseraContributed PerKinoSearch1::Search::BooleanQuery(3)

NAME
       KinoSearch1::Search::BooleanQuery - match boolean combinations of
       Queries

SYNOPSIS
	   my $bool_query = KinoSearch1::Search::BooleanQuery->new;
	   $bool_query->add_clause( query => $term_query, occur => 'MUST' );
	   my $hits = $searcher->search( query => $bool_query );

DESCRIPTION
       BooleanQueries are super-Query objects which match boolean combinations
       of other Queries.

       One way of producing a BooleanQuery is to feed a query string along the
       lines of "this AND NOT that" to a QueryParser object:

	   my $bool_query = $query_parser->parse( 'this AND NOT that' );

       It's also possible to achieve the same end by manually constructing the
       query piece by piece:

	   my $bool_query = KinoSearch1::Search::BooleanQuery->new;

	   my $this_query = KinoSearch1::Search::TermQuery->new(
	       term => KinoSearch1::Index::Term->new( 'bodytext', 'this' ),
	   );
	   $bool_query->add_clause( query => $this_query, occur => 'MUST' );

	   my $that_query = KinoSearch1::Search::TermQuery->new(
	       term => KinoSearch1::Index::Term->new( 'bodytext', 'that' ),
	   );
	   $bool_query->add_clause( query => $that_query, occur => 'MUST_NOT' );

       QueryParser objects and hand-rolled Queries can work together:

	   my $general_query = $query_parser->parse($q);
	   my $news_only     = KinoSearch1::Search::TermQuery->new(
	       term => KinoSearch1::Index::Term->new( 'category', 'news' );
	   );
	   $bool_query->add_clause( query => $general_query, occur => 'MUST' );
	   $bool_query->add_clause( query => $news_only,     occur => 'MUST' );

METHODS
   new
	   my $bool_query = KinoSearch1::Search::BooleanQuery->new;

       Constructor. Takes no arguments.

   add_clause
	   $bool_query->add_clause(
	       query => $query, # required
	       occur => 'MUST', # default: 'SHOULD'
	   );

       Add a clause to the BooleanQuery.  Takes hash-style parameters:

       ·   query - an object which belongs to a subclass of
	   KinoSearch1::Search::Query.

       ·   occur - must be one of three possible values: 'SHOULD', 'MUST', or
	   'MUST_NOT'.
