Hi. There is an index having arround 200 million documents. I want to scroll over all its documents, so I prefered to use sliced scroll to do so, but every time I use scroll for this index, after some minutes of getting responses, I can't get responses anymore, and it keeps waiting till the scroll time is over. I have tried this for indices with 50 and 100 million documents, and it works well, but when it comes to indices having about 200 million documents, it freezes.
What should I do?
Thank you for any help you can offer.
