• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y lang xa hoi. chieu ((tu cham) OR (thi cham)) xuc van hanh ((bai cua) OR (lai cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y lang xa hoi. chieu ((tu cham) OR (thi cham)) xuc van hanh ((bai cua) or (lai cua)) tre".
• Adding a wildcard symbol may retrieve word variants: su sach y lang xa hoi. chieu ((tu cham) OR (thi cham)) xuc van hanh ((bai cua) or (lai cua)) tre*.
