exactly. An update is a delete and create behind the scene.

Oh, it is interesting. I really had some suggestions with new payloads and some with old! Thank you for explain! As I understand, Lucene perform update operation as delete old document and create new document?
Your idea with alias looks great. I think we will use it for the next full reindex, thank you again.

TBH, I'd prefer using another index with an alias on top of the older one and at the end, switch the alias to the new one and delete old index.

Yes, exactly. I update docs in the same index.

So you "update" docs, right?

Thank you, David!
I need to call _optimize by hands to refresh payloads in completion suggester. This method is recommended here: http://www.elasticsearch.org/guide/en/elasticsearch/reference/0.90/search-suggesters-completion.html. For some reason _suggest returns old payloads after reindexing on our stage server. I don't know why, completion suggester on my local instance of ElasticSearch updates on the fly. Maybe because our stage index is 10Gb size and contains 10 millions documents and my local index has only 180 000 documents.

In 99.9% you should not call optimize api and let elasticsearch/Lucene do it for you when needed.
To answer to your question, yes search and index operations will still possible during that time.

Hello!
Can anyone tell is it safe to call _optimize under normal production work? Will search requests be responded and indexing be performed?
