Seems scrolling and scanning is not supported over multiple indexes...is there any way around this ?
Sample query
GET sales-rpts3*/ptt/_search?scroll=1m
{
  "size": 5
}
Response:
{
   "error": {
	  "root_cause": [
		 {
			"type": "array_index_out_of_bounds_exception",
			"reason": "98"
		 }
	  ],
	  "type": "array_index_out_of_bounds_exception",
	  "reason": "98"
   },
   "status": 500
}
