and what this Meaning

refresh
For refresh operations. Thread pool type is scaling with a keep-alive of 5m and a max of min(10, (# of available processors)/2).
if cpu is 8 core, the min is 32 the max is 32*(104)?

Don't post images for code.

I can suspect you are using tabs instead of spaces but that's just a guess.

So the percolate thread pool has been removed since 5.0 and the percolator uses the search thread pool instead. The reason behind this is that the percolate api has been replaced by the percolate query that can be used in the search api.

@mvg
where to see the thread pool set api ?
thanks.
