• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky ((((sang lap) OR (sang ma))) or (sang tai)) hai. hieu ve cam xuc va danh vai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky ((((sang lap) OR (sang ma))) OR (sang tai)) hai. hieu ve cam xuc va danh vai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky ((((sang lap) OR (sang ma))) or (sang tai)) hai. hieu ve cam xuc va danh vai cua te".
• Adding a wildcard symbol may retrieve word variants: su sach ky ((((sang lap) OR (sang ma))) or (sang tai)) hai. hieu ve cam xuc va danh vai cua te*.
