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