• Performing a fuzzy search may retrieve terms with similar spellings: tu sach y dang ((xay hoi) OR (tay hoi)). hieu ((va cham) or (tu cham)) luc va doan cap cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y dang ((xay hoi) OR (tay hoi)). hieu ((va cham) OR (tu cham)) luc va doan cap cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y dang ((xay hoi) OR (tay hoi)). hieu ((va cham) or (tu cham)) luc va doan cap cua te*".
