• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc chieu) OR (hoc thieu)) xanh - hanh trung cao thuong thong den ((ran cau) OR (ban cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc chieu) or (hoc thieu)) xanh - hanh trung cao thuong thong den ((ran cau) OR (ban cau))~".
• Adding a wildcard symbol may retrieve word variants: ((hoc chieu) or (hoc thieu)) xanh - hanh trung cao thuong thong den ((ran cau) OR (ban cau))*.
