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