• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sach) OR (thuat san)) ky nang xa hoi. hieu ve cac duc va ((thanh vi) OR (thanh ve)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sach) or (thuat san)) ky nang xa hoi. hieu ve cac duc va ((thanh vi) OR (thanh ve)) cua te".
• Adding a wildcard symbol may retrieve word variants: ((vu sach) or (thuat san)) ky nang xa hoi. hieu ve cac duc va ((thanh vi) OR (thanh ve)) cua te*.
