Dear All, I am learning and evaluating the EC; and I have 2 questions about document update and delete in EC. First of all, if I want to update a document, do I just submit a new post with the same ID to the EC? I have tried the steps and after submitting in that way, The document no longer returns. In fact, I cannot find any example on how to update doc on EC website. Next, does the space of all deleted docs release NRT? If not, how can I get back the space? Thanks a lot. ---

Not sure I understand the questions. You update a document by indexing the full document with the new data. Did not understand the second question on deleted docs and release NRT?

The deleted docs stay in the underlying Lucene index until the next merge of that index segment. > **[Elasticsearch Platform — Find real-time answers at scale](https://www.elastic.co)** > > Power insights and outcomes with the Elasticsearch Platform and AI.

Yes, they are, though just to complete the picture, they are "invisible" when searching (on the next refresh).
