• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc thieu) OR (chao chu)) xanh - hanh trung ((cua dung) OR (cua dang)) huong doan van ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) or (chao chu)) xanh - hanh trung ((cua dung) OR (cua dang)) huong doan van ban".
