• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((bai ky) OR (sai ky)) ((lang ha) OR (dang van)) hoi. hieu va cam luoc van anh dao cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((bai ky) OR (sai ky)) ((lang ha) or (dang van)) hoi. hieu va cam luoc van anh dao cua triet".
