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