Divided data to many index in output logstash

Elastic Stack Logstash
1

Hello,
I want to config logstash to push in 2 index 1 day.
If date time in logs between 00:00 to 11:59, I want to push it in index logstash-%YYYY.MM.dd-1.
If date time in logs between 12:00 to 23:59, I want to push it in index logstash-%YYYY.MM.dd-2.

Please help me with this solution.
Thank you.

> Aug 10 15:41:15 server001 haproxy[1889]: 107.113.167.5:32075
