• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky ((dang xa) OR (lang xa)) hoi. hieu va nam ((luc va) OR (loc va)) danh vai cua te.
• Adding a wildcard symbol may retrieve word variants: tu sac ky ((dang xa) or (lang xa)) hoi. hieu va nam ((luc va) or (loc va)) danh vai cua te*.
