• If you are trying to use Boolean operators, they must be ALL CAPS: ((((hoi tieu) OR (hoi tiep))) OR (doi chieu)) tinh - hinh dinh cuu dang cong dan thanh cac*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((hoi tieu) OR (hoi tiep))) or (doi chieu)) tinh - hinh dinh cuu dang cong dan thanh cac*".
