Non collocated subqueries

Hello,



It seems that SqlFieldsQuery.setCollocated and
SqlFieldsQuery.setDistributedJoins has no affect on subqueries under IN and
EXISTS expressions. I didn’t find any information about subqueries specific in
actual documentation.



Subqueries is important part of sql, please describe it in documents.

For example, EXISTS subqueries is usefull with hibernate criteria, when you
need select “child” entity but filter by field in “parent” entity
