Hi all, I have a question.
In my index I have two fields that I want merge into a third field and than I whish to hash this "new field" using elasticsearch' script processor.
After running the script I would like to have a new field which is the sha1 hash of the merge of field1 and field2
It is possible to do that without reindex? Or a reindex is needed?
A simple 32 bit hashing is enough to save the performances of es, sha1 is just for explain the example
Can someone help me please?
My version of elasticsearch is 7.1.1
