Kibana vega map

Hi guys , right now i'm working on some vega map visualization , so i had a problem with the size of the documents to load which is per default 10000 doc , so i passed the problem by increasing index.max_result_window to 10000000 , then i was working with 50000 doc but now when i loaded 4 million doc in elasticsearch i changed the size of the documents to load to 5000000 but i'm having problems when i fix the time filter to a 6 months or even higher it won't work , it works only with the lask week or the yesterday (in time filter)

kibana version 7.2
thanks.

@nyuriks can you please take a look ? Any logs which support ur case ? Screenshots will be helpful too.

Thanks
