• If you are trying to use Boolean operators, they must be ALL CAPS: luyen tap cac khu đe co ban ve y ((((thi cuong) OR (thi truong))) OR (thi hong)) dung*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "luyen tap cac khu đe co ban ve y ((((thi cuong) OR (thi truong))) or (thi hong)) dung*".
