Updating a document using Java API

Elastic Stack Elasticsearch
1

Hi All,

As part of an update request, I need to add new fields to a document(search
to get the doc-id and then update).

With Lucene API's it can be achieved by 1) reading the doc into a temp
document 2) update the temp document 3) delete the original document from
index and add the temp document.

How does update work in ES. It is also delete and add a new document?

My index has some un-stored fields. Is there a way to keep the un-stored
field after the update or they are lost in ElasticSearch?

Would appreciate any pointers you might have.

Thanks!

Neera

Are you storing the document source? If so, you can use the update API. If
not, you would need to reindex from the original source.
