• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((thiet tach) OR (thien hach)) - thanh trung tuan bang phuong van ((toan cau) OR (toan tap))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((thiet tach) OR (thien hach)) - thanh trung tuan bang phuong van ((toan cau) or (toan tap))*".
