    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)]
                }

    );
```

## 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"
