• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (doi chieu)) sang - hanh mang cua dang dung ((thanh hoa) OR (thanh san)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (doi chieu)) sang - hanh mang cua dang dung ((thanh hoa) or (thanh san)) cau~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) OR (doi chieu)) sang - hanh mang cua dang dung ((thanh hoa) or (thanh san)) cau*.
