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