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