• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((hieu manh) OR (chieu sang)) - canh doanh cua nhung ((cong manh) OR (cong thanh)) toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((hieu manh) or (chieu sang)) - canh doanh cua nhung ((cong manh) OR (cong thanh)) toan tap~".
• Adding a wildcard symbol may retrieve word variants: ho ((hieu manh) or (chieu sang)) - canh doanh cua nhung ((cong manh) OR (cong thanh)) toan tap*.
