• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac huy hoang van hoc. ((hieu va) OR (hieu qua)) cam duc ((van hanh) OR (van anh)) vi cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac huy hoang van hoc. ((hieu va) or (hieu qua)) cam duc ((van hanh) OR (van anh)) vi cua triet*".
