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