    my $query = Search::GIN::Query::Set->new(
        operation => 'INTERSECT',
        subqueries => [
            Search::GIN::Query::Manual->new(

    );

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"
