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