• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc thieu) OR (hoc hien)) xanh - thanh trung cua nhung ((cong thanh) OR (cong tan)) cha tu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) or (hoc hien)) xanh - thanh trung cua nhung ((cong thanh) OR (cong tan)) cha tu*".
