• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sach) OR (thuat sach)) 6 tang ma hoi. hieu ve ((cham lo) OR (cam lo)) van hanh lai cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu sach) OR (thuat sach)) 6 tang ma hoi. hieu ve ((cham lo) or (cam lo)) van hanh lai cua te*".
