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