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