• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc chieu) OR (hoc thieu)) xanh - hanh trung va nhung cong ((dan than) OR (ban than)) cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc chieu) or (hoc thieu)) xanh - hanh trung va nhung cong ((dan than) OR (ban than)) cao".
