• If you are trying to use Boolean operators, they must be ALL CAPS: so ((sanh y) OR (anh y)) tang ma hoi. hieu ((ve cam) OR (ve cac)) tuc van hanh lai cua viet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so ((sanh y) OR (anh y)) tang ma hoi. hieu ((ve cam) or (ve cac)) tuc van hanh lai cua viet*".
