• If you are trying to use Boolean operators, they must be ALL CAPS: toc sac ky ((lang ha) OR (dang van)) hoi. hieu ha nam thuc ((day dan) OR (dao dan)) tai buu tre.
• Adding a wildcard symbol may retrieve word variants: toc sac ky ((lang ha) or (dang van)) hoi. hieu ha nam thuc ((day dan) or (dao dan)) tai buu tre*.
