这是我的日志格式（为了演示而简化）
2018-04-12 14:43:00.000 ERROR hello
2018-04-12 14:44:01.000 ERROR world
2018-04-12 14:44:03.000 INFO this is a multi-line log
NOTICE THIS LINE, this line is also part of the log
2018-04-12 14:46:00.000 INFO foo
那么如何过滤日志[2018-04-12 14:44:00.000, 2018-04-12 14:45:00.000)以产生以下输出呢？
2018-04-12 14:44:01.000 ERROR world
2018-04-12 14:44:03.000 INFO this is a multi-line log
NOTICE THIS LINE, this line is also part of the log
