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