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"
