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