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