KinoSearch1::Search::MultiSearcher(3pm) 		User Contributed Perl Documentation		   KinoSearch1::Search::MultiSearcher(3pm)

Dummy class, only here to support initialization of Weights from Queries.

NAME

       KinoSearch1::Search::MultiSearcher - Aggregate results from multiple searchers.

SYNOPSIS

	   for my $server_name (@server_names) {
	       push @searchers, KinoSearch1::Search::SearchClient->new(
		   peer_address => "$server_name:$port",
		   analyzer	=> $analyzer,
		   password	=> $pass,
	       );
	   }
	   my $multi_searcher = KinoSearch1::Search::MultiSearcher->new(
	       searchables => @searchers,
	       analyzer    => $analyzer,
	   );
	   my $hits = $multi_searcher->search( query => $query );

DESCRIPTION

       Aside from the arguments to its constructor, MultiSearcher looks and acts just like a KinoSearch1::Searcher object.

       The primary use for MultiSearcher is to aggregate results from several remote searchers via SearchClient, diffusing the cost of searching a
       large corpus over multiple machines.

METHODS

   new
       Constructor.  Takes two hash-style parameters, both of which are required.

       o   analyzer - an item which subclasses KinoSearch1::Analysis::Analyzer.

       o   searchables - a reference to an array of searchers.

KinoSearch1::Search::BooleanQuery(3pm)			User Contributed Perl Documentation		    KinoSearch1::Search::BooleanQuery(3pm)

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:

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

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