• If you are trying to use Boolean operators, they must be ALL CAPS: tuyen tai ((((cac khu) OR (cac kieu))) OR (cac che)) đe co ban ve y te cong luong.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tuyen tai ((((cac khu) OR (cac kieu))) or (cac che)) đe co ban ve y te cong luong".
