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!

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. > **[Elasticsearch Platform — Find real-time answers at scale](https://www.elastic.co)** > > Power insights and outcomes with the Elasticsearch Platform and AI.
