• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho hieu) OR (ho chieu)) lang - ((hanh tang) OR (hanh trang)) luan nhung cong tac phan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho hieu) OR (ho chieu)) lang - ((hanh tang) or (hanh trang)) luan nhung cong tac phan cau~".
• Adding a wildcard symbol may retrieve word variants: ((ho hieu) OR (ho chieu)) lang - ((hanh tang) or (hanh trang)) luan nhung cong tac phan cau*.
