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