• If you are trying to use Boolean operators, they must be ALL CAPS: nuoc sach ly hang xa hoi. ((hieu va) OR (hieu qua)) cac lo ((va hanh) OR (va thanh)) vai cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "nuoc sach ly hang xa hoi. ((hieu va) OR (hieu qua)) cac lo ((va hanh) or (va thanh)) vai cua triet*".
