• If you are trying to use Boolean operators, they must be ALL CAPS: ho lieu tinh - manh hung cap duong ((((cong dan) OR (cong san))) OR (cong tan)) toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho lieu tinh - manh hung cap duong ((((cong dan) OR (cong san))) or (cong tan)) toan cau".
• Adding a wildcard symbol may retrieve word variants: ho lieu tinh - manh hung cap duong ((((cong dan) OR (cong san))) or (cong tan)) toan cau*.
