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