• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - ((((hanh trang) OR (thanh trung))) OR (hanh trinh)) cua thong thong san phan tu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - ((((hanh trang) OR (thanh trung))) or (hanh trinh)) cua thong thong san phan tu~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - ((((hanh trang) OR (thanh trung))) or (hanh trinh)) cua thong thong san phan tu*.
