Hi Luca,
Thanks a lot for the response and the example,
But we have a fruit keyword which is created and the only thing is we are populating different value to get the total count.
My issue is this -- I have one keyword named as service where i get two different values.
this is how my data table looks now
But i want a filter value in kibana or logstash that both the service.keyword output as you see should be merged to a new , Which will be called as -- > FIRST NID CARD and also the count of both the values should be added to it.
