• If you are trying to use Boolean operators, they must be ALL CAPS: doc ((hieu xanh) OR (chieu xanh)) - thanh trang va thong cong san ((than cap) OR (khan cap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc ((hieu xanh) OR (chieu xanh)) - thanh trang va thong cong san ((than cap) or (khan cap))~".
• Adding a wildcard symbol may retrieve word variants: doc ((hieu xanh) OR (chieu xanh)) - thanh trang va thong cong san ((than cap) or (khan cap))*.
