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¶

ATTRIBUTES¶
subqueries¶

operation¶
One of the basic set operators: "UNION", "INTERSECT" and
