• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty ((((nang xa) OR (mang xa))) OR (lang xa)) hoi. hieu va cham trung va danh le cua te~.
• Adding a wildcard symbol may retrieve word variants: tu sach ty ((((nang xa) or (mang xa))) or (lang xa)) hoi. hieu va cham trung va danh le cua te*.
