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