• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((ty xang) OR (ly hang)) xa hoi. lieu va cam duc ((va dinh) OR (va kinh)) dien cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((ty xang) or (ly hang)) xa hoi. lieu va cam duc ((va dinh) OR (va kinh)) dien cua triet".
