• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc hiem) OR (hoc thieu)) ngan - hanh trang ((cua thong) OR (cua tong)) thong cua phuong cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc hiem) OR (hoc thieu)) ngan - hanh trang ((cua thong) or (cua tong)) thong cua phuong cau~".
• Adding a wildcard symbol may retrieve word variants: ((hoc hiem) OR (hoc thieu)) ngan - hanh trang ((cua thong) or (cua tong)) thong cua phuong cau*.
