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