• If you are trying to use Boolean operators, they must be ALL CAPS: vu khach y lang xa hoi. hieu ((ve cam) OR (ve cac)) luc ((va hang) OR (va lang)) cua cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu khach y lang xa hoi. hieu ((ve cam) or (ve cac)) luc ((va hang) OR (va lang)) cua cua triet".
