• Performing a fuzzy search may retrieve terms with similar spellings: su sach ta tang ha hoi. hieu ((ve cham) OR (ve chat)) tuc xa ((danh vai) or (doanh van)) cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ta tang ha hoi. hieu ((ve cham) OR (ve chat)) tuc xa ((danh vai) OR (doanh van)) cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ta tang ha hoi. hieu ((ve cham) OR (ve chat)) tuc xa ((danh vai) or (doanh van)) cuu tre*".
