NAME

       Search::GIN::Query::Set - Create queries with set operations

VERSION

       version 0.08

SYNOPSIS

	   # build a query like:
	   # (type:pdf OR type:png) AND (name:Homer OR name:Bart)

	   use Search::GIN::Query::Set;
	   use Search::GIN::Query::Manual;

	   my $query = Search::GIN::Query::Set->new(
	       operation => 'INTERSECT',
	       subqueries => [
		   Search::GIN::Query::Manual->new(
		       values => {
			  type => [qw(pdf png)]
		       }
		   ),
		   Search::GIN::Query::Manual->new(
		       values => {
			  name => [qw(Homer Bart)]
		       }
		   ),
	       ]
	   );

DESCRIPTION

       Creates a manual GIN query that can be used to search using basic set theory, in order to build more complex queries.

       This query doesn't provide any specific search, it's just a set operator for subqueries. You can build complex queries by using other set
       queries as subqueries for a set query.

METHODS
/SUBROUTINES
   new
       Creates a new query.

ATTRIBUTES

   subqueries
       The subqueries to process

   operation
       One of the basic set operators: "UNION", "INTERSECT" and "EXCEPT". The default is "UNION"
