• If you are trying to use Boolean operators, they must be ALL CAPS: ((done sin) OR (done using)) ka a brain aging tan ((hong ng) OR (dang hari)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((done sin) OR (done using)) ka a brain aging tan ((hong ng) or (dang hari)) ;*".
