• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((bien tinh) OR (trieu tinh)) - thanh trung cua dung ((cong tap) OR (cong tan)) quang tri*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((bien tinh) or (trieu tinh)) - thanh trung cua dung ((cong tap) OR (cong tan)) quang tri*".
