Different index for different logs

Need different index for each log file path.
1> access log in access.conf file -> same server
2> csv file in task_engine.csv -> same server

Need to have task_engine.csv file in different index so that I can pull it in machine learning .

Issue: I am not getting task_engine.csv file at all, when I start manually it works but I am seeing acecess logs as well in the same index. I need it to work without manual start, more over need to have task_engine.csv in different index so I can use it in machine learning.

OS: RHEL 7
Logstash version: logstash-6.7.1-1.noarch
