• If you are trying to use Boolean operators, they must be ALL CAPS: doc ((chieu xanh) OR (chieu sach)) - hanh trung cua nhung tuong dan ((than cau) OR (than cap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc ((chieu xanh) OR (chieu sach)) - hanh trung cua nhung tuong dan ((than cau) or (than cap))~".
• Adding a wildcard symbol may retrieve word variants: doc ((chieu xanh) OR (chieu sach)) - hanh trung cua nhung tuong dan ((than cau) or (than cap))*.
