Steve Ebersole closed HHH-2647.
-------------------------------
Assignee: Steve Ebersole
Resolution: Rejected
The first phase of the query parser actually groups and aligns the predicates according to
your parenthesis; it changes the order in which they are evaluated (imagine, just like
would happen in the sql's query translator!).
@Guillaume, @Denis Would it be ideal to be able to match the parenthesis from the input
string into the output string. Well *perhaps* (I personally think it is not necessary
since as y'all are finding out the results are consistent). However, this *will not*
happen unless someone steps up and produces a patch for this. It is extremely difficult
to do and you get zero benefit for all that effort.

AND ( ( 1 AND 2 ) OR ( 3 AND 4 ) OR ( 5 AND 6 ) )
