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