• Performing a fuzzy search may retrieve terms with similar spellings: hoc sach ky ((dang mai) OR (dang bai)) hoi. hieu van cam xuc van anh vi ((cua te) or (ve triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc sach ky ((dang mai) OR (dang bai)) hoi. hieu van cam xuc van anh vi ((cua te) OR (ve triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc sach ky ((dang mai) OR (dang bai)) hoi. hieu van cam xuc van anh vi ((cua te) or (ve triet))".
