• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sac) or (tu cac)) ky ((sang lai) OR (mang lai)) hoi. hieu su cao tu va danh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sac) OR (tu cac)) ky ((sang lai) OR (mang lai)) hoi. hieu su cao tu va danh vi cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sac) or (tu cac)) ky ((sang lai) OR (mang lai)) hoi. hieu su cao tu va danh vi cua te*".
