• If you are trying to use Boolean operators, they must be ALL CAPS: theo tieu xanh - anh tang cua dang nong dan ((than cau) OR (((than cap) OR (khan cap))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo tieu xanh - anh tang cua dang nong dan ((than cau) or (((than cap) OR (khan cap))))~".
• Adding a wildcard symbol may retrieve word variants: theo tieu xanh - anh tang cua dang nong dan ((than cau) or (((than cap) OR (khan cap))))*.
