• If you are trying to use Boolean operators, they must be ALL CAPS: ((toc sach) OR (thuoc sach)) v nang xa hoi. ((hieu va) OR (lieu va)) cam xuc van anh d vao triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((toc sach) OR (thuoc sach)) v nang xa hoi. ((hieu va) or (lieu va)) cam xuc van anh d vao triet*".
