I have a very simple question :
I want to update multiple documents to elasticsearch. Sometimes the document already exists but sometimes not. I don't want to use a get request to check the existence of the document (this is decreasing my performance). I want to use directly my update request to index the document directly if it doesn't exist yet.
I know that we can use upsert to create a non existing field when updating a document, but this is not what I want. I want to index the document if it doesn't exist. I don't know if upsert can do this.
Can you provide me some explaination ?
Thanks in advance!
