• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky dang van hoi. hieu ((va cam) OR (va cao)) xuc va hoang hai ((cua tre) OR (va triet))~.
• Adding a wildcard symbol may retrieve word variants: tu sach ky dang van hoi. hieu ((va cam) or (va cao)) xuc va hoang hai ((cua tre) or (va triet))*.
