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