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