Как объединить строку из документов в список строк
Lets say I have ES records like this:
{ "customerId": 1, "address": "hotel1:1, hotel2:2" "week" : 1 } { "customerId": 2, "address": "hotel3:1, hotel4:2" "week" : 2 } Now I want to concat address into 1
{ "customerId": 2, "address": "hotel3:1, hotel4:2", "hotel1:1, hotel2:2" } Is there a way in Elastic Search or Java API to concatenate strings while aggregating?
