• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (vu sach)) ky trong van hoi. hieu van cam ((xuc va) OR (tuc va)) hanh vi cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) OR (vu sach)) ky trong van hoi. hieu van cam ((xuc va) or (tuc va)) hanh vi cua triet".
