[syslog-ng]Archiving log file

I wish to split the log file into daily basis by means of different file per day according to the received timestamp. Is there any option in syslog-ng can be configured for this. At normal, the log file will grow bigger and bigger and become more difficult to read especially when we want to search for certain event on certain date. By achiving the log into daily file with meaningful filename, it should be much more convenient. Perhaps if syslog-ng do not have this option, is there any workaround or better method to due with this? Regards
