• If you are trying to use Boolean operators, they must be ALL CAPS: ho thien hach - thanh ((truong cua) OR (truong ca)) dung cong tan ((toan cau) OR (toan cao))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho thien hach - thanh ((truong cua) OR (truong ca)) dung cong tan ((toan cau) or (toan cao))*".
