• If you are trying to use Boolean operators, they must be ALL CAPS: doi chi xanh - thanh trung ((((qua dung) OR (quang dung))) OR (cua dang)) cong van than cap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chi xanh - thanh trung ((((qua dung) OR (quang dung))) or (cua dang)) cong van than cap".
• Adding a wildcard symbol may retrieve word variants: doi chi xanh - thanh trung ((((qua dung) OR (quang dung))) or (cua dang)) cong van than cap*.
