• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky ((dang xa) OR (((dang van) OR (hang va)))) hoi. hieu ve cac dac ban hanh hai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky ((dang xa) or (((dang van) OR (hang va)))) hoi. hieu ve cac dac ban hanh hai cua triet".
