how to remove headings of a log file?

[SapthagiriAavik]

i indexed my log file line by line using regex, i want only valid rows not headings and lines , but in my query results those headings and lines are included. How to omit those in results?

my log file sample

SNAP_TIME app Sector MEMBER NO_HANDLE PRIVATE_SORT

You can try adding HEADER_FIELD_LINE_NUMBER OR FIELD_HEADER_REGEX in props.conf:
