• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((lieu tinh) OR (nhieu tang)) - thanh trung ma dung cong thanh ((toan cau) OR (toan tap))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((lieu tinh) or (nhieu tang)) - thanh trung ma dung cong thanh ((toan cau) OR (toan tap))*".
