• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky nang xa hoi. ((hieu hien) or (hieu ve)) bach tuoc va hanh vi ((cuu tre) OR (cau treo))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky nang xa hoi. ((hieu hien) OR (hieu ve)) bach tuoc va hanh vi ((cuu tre) OR (cau treo))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky nang xa hoi. ((hieu hien) or (hieu ve)) bach tuoc va hanh vi ((cuu tre) OR (cau treo))*".
