• If you are trying to use Boolean operators, they must be ALL CAPS: ((mot chieu) OR (hoc thieu)) tinh - hanh trung cap ((dong cong) OR (duong cong)) tang thanh chau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((mot chieu) or (hoc thieu)) tinh - hanh trung cap ((dong cong) OR (duong cong)) tang thanh chau".
• Adding a wildcard symbol may retrieve word variants: ((mot chieu) or (hoc thieu)) tinh - hanh trung cap ((dong cong) OR (duong cong)) tang thanh chau*.
