I'm trying to write a mapreduce job where I can query elasticsearch so it
can return to me specific fields. Is there any way to do that?
My mapping contains about 30 fields and I will need just 4 of them
("_id","title","description","category")
The way I was doing it is to process each answer to get those fields, but
I'm looking for a cleaner way to do that.
Any help or suggestion is appreciated.
Thanks!
