use the scan method e g    curl -XGET  localhost 9200  search search type scan amp scroll 10m amp size 50  -d           query              match all                   see here

Another approach is to first do a searchType   count   then and then do a normal search with size set to results count   The advantage here is it avoids depending on a magic number for UPPER BOUND as suggested in this similar SO question  and avoids the extra overhead of building too large of a priority queue that Shay Banon describes here  It also lets you keep your results sorted  unlike scan   The biggest disadvantage is that it requires two requests  Depending on your circumstance  this may be acceptable

From the docs   Note that from   size can not be more than the index max result window index setting which defaults to 10 000   So my admittedly very ad-hoc solution is to just pass size  10000 or 10 000 minus from if I use the from argument    Note that following Matt s comment below  the proper way to do this if you have a larger amount of documents is to use the scroll api  I have used this successfully  but only with the python interface

You can use the from and size parameters to page through all your data   This could be very slow depending on your data and how much is in the index    http   www elastic co guide en elasticsearch reference current search-request-from-size html
