• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y nang x hoi. hieu ve tac dung ban ((thanh loi) OR (thanh lap)) ((cua triet) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y nang x hoi. hieu ve tac dung ban ((thanh loi) OR (thanh lap)) ((cua triet) or (cua te))".
