• If you are trying to use Boolean operators, they must be ALL CAPS: cho ((chu xanh) OR (chieu xanh)) - hanh dung ((quan dung) OR (qua dung)) cong van tai cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "cho ((chu xanh) OR (chieu xanh)) - hanh dung ((quan dung) or (qua dung)) cong van tai cao".
