• Performing a fuzzy search may retrieve terms with similar spellings: thuoc ((sach ty) or (sach thu)) nano xa hoi. thien van cam xuc va ((danh vai) OR (danh sai)) cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuoc ((sach ty) OR (sach thu)) nano xa hoi. thien van cam xuc va ((danh vai) OR (danh sai)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuoc ((sach ty) or (sach thu)) nano xa hoi. thien van cam xuc va ((danh vai) OR (danh sai)) cua te".
• Adding a wildcard symbol may retrieve word variants: thuoc ((sach ty) or (sach thu)) nano xa hoi. thien van cam xuc va ((danh vai) OR (danh sai)) cua te*.
