Result window is too large, from + size must be less than or equal to: [10000] but was [1000000]. See the scroll api for a more efficient way to request large data sets. This limit can be set by changing the [index.max_result_window] index level parameter
I suppose the proper fix would be to modify the code to use the scroll API, but for a quick fix, you can use the following:
curl -XPUT http://localhost:9200/doraana/_settings -d '{ "index" : { "max_result_window" : 1000000 } }'
With Elastic server: http://localhost:9200/doraana
, with index: doraana
