• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu xanh - nhanh lang ha nhung ((cong van) OR (cong san)) ((than ban) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu xanh - nhanh lang ha nhung ((cong van) OR (cong san)) ((than ban) or (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: theo chieu xanh - nhanh lang ha nhung ((cong van) OR (cong san)) ((than ban) or (toan ban))*.
