• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sac) OR (thuy san)) ky ((nang xa) OR (nang x)) hoi. hieu van nam tu va thanh van cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sac) or (thuy san)) ky ((nang xa) OR (nang x)) hoi. hieu van nam tu va thanh van cua triet".
