• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) or (te sach)) ky dang xa hoi. nhieu viec cua xuc may tinh di ((cuu tre) OR (cau treo))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) ky dang xa hoi. nhieu viec cua xuc may tinh di ((cuu tre) OR (cau treo)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (te sach)) ky dang xa hoi. nhieu viec cua xuc may tinh di ((cuu tre) OR (cau treo))".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (te sach)) ky dang xa hoi. nhieu viec cua xuc may tinh di ((cuu tre) OR (cau treo))*.
