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