• If you are trying to use Boolean operators, they must be ALL CAPS: tu dan ky nang x hoi. hieu ((((va cam) OR (ve cai))) OR (ve cac)) duc van hanh khai cua te.
• Adding a wildcard symbol may retrieve word variants: tu dan ky nang x hoi. hieu ((((va cam) or (ve cai))) or (ve cac)) duc van hanh khai cua te*.
