ES does not return all the records by default, you will have to pass
thepage size in request. Other way to do this to use count query first the
pass the size in 2nd query.
I tried with passing size as Max integer but some time it started going OOM
because Lucene allocates memory to size passed in request.

Best way is to count first then pass the size in 2nd query.

I'd prefer using scroll API.
