• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ly ((vang ma) OR (tang ma)) hoi. hieu ((ve cam) or (ve cham)) duc va thanh de cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ly ((vang ma) OR (tang ma)) hoi. hieu ((ve cam) OR (ve cham)) duc va thanh de cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ly ((vang ma) OR (tang ma)) hoi. hieu ((ve cam) or (ve cham)) duc va thanh de cua te*".
