• If you are trying to use Boolean operators, they must be ALL CAPS: vu thanh ky nang x hoi. hieu ((ve cham) OR (ve chat)) thuc ((day hanh) OR (day nhanh)) tue cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu thanh ky nang x hoi. hieu ((ve cham) OR (ve chat)) thuc ((day hanh) or (day nhanh)) tue cua tre*".
