• If you are trying to use Boolean operators, they must be ALL CAPS: chao ((chu tinh) OR (chua tinh)) - nhanh ((thang van) OR (thanh van)) nang cong dan than tap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "chao ((chu tinh) OR (chua tinh)) - nhanh ((thang van) or (thanh van)) nang cong dan than tap".
• Adding a wildcard symbol may retrieve word variants: chao ((chu tinh) OR (chua tinh)) - nhanh ((thang van) or (thanh van)) nang cong dan than tap*.
