• If you are trying to use Boolean operators, they must be ALL CAPS: tu san ky ((mang xa) OR (nang x)) hoi. hieu ve cam suc ((manh hanh) OR (dang thanh)) tai cuu tre.
• Adding a wildcard symbol may retrieve word variants: tu san ky ((mang xa) or (nang x)) hoi. hieu ve cam suc ((manh hanh) or (dang thanh)) tai cuu tre*.
