• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu xanh) OR (chieu sang)) - ((anh hang) OR (anh bang)) cua thong cong tap quan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) or (chieu sang)) - ((anh hang) OR (anh bang)) cua thong cong tap quan cao~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) or (chieu sang)) - ((anh hang) OR (anh bang)) cua thong cong tap quan cao*.
