• If you are trying to use Boolean operators, they must be ALL CAPS: (tuyen OR quyen) tap cac chien đe co ban ve _ te ((((cong cong) OR (dung cong))) OR (trong cong))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(tuyen OR quyen) tap cac chien đe co ban ve _ te ((((cong cong) or (dung cong))) or (trong cong))~".
• Adding a wildcard symbol may retrieve word variants: (tuyen OR quyen) tap cac chien đe co ban ve _ te ((((cong cong) or (dung cong))) or (trong cong))*.
