• 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 duc va thanh lap ((cua viet) OR (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 duc va thanh lap ((cua viet) or (cua vat))".
• Adding a wildcard symbol may retrieve word variants: ((te sach) OR (toc sach)) ky nang xa hoi. thi van cac duc va thanh lap ((cua viet) or (cua vat))*.
