• If you are trying to use Boolean operators, they must be ALL CAPS: su sai ky nang ((x hoi) OR (xa hoi)). hieu ((ve cac) OR (va cam)) xuc van hanh vu ve triet.
• Adding a wildcard symbol may retrieve word variants: su sai ky nang ((x hoi) or (xa hoi)). hieu ((ve cac) or (va cam)) xuc van hanh vu ve triet*.
