• If you are trying to use Boolean operators, they must be ALL CAPS: (cuoc OR duoc) cach y ((sang ma) OR (sang tao)) hoa. hieu ve cau duc va hanh vai cua viet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(cuoc or duoc) cach y ((sang ma) OR (sang tao)) hoa. hieu ve cau duc va hanh vai cua viet*".
