• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac ky ((nang xa) OR (nang x)) hoi. lieu va ((tham cuu) OR (tham cung)) ban hanh vai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ky ((nang xa) or (nang x)) hoi. lieu va ((tham cuu) OR (tham cung)) ban hanh vai cua triet".
