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