• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ly hang dau hoi. hieu va cam ((((tuc va) OR (thuc va))) OR (duc va)) danh vi cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ly hang dau hoi. hieu va cam ((((tuc va) OR (thuc va))) or (duc va)) danh vi cua triet".
