Hi, when I create new document and call prepareIndex it overwrites an existing one (was created just a nanosecond before this using another thread). Is it possible to use ES versions to control this behavior like when doing updates? Problem is, that when document exists I can receive its version prior to update and check if I'm updating correct version of document - this is working. But when document is not in ES - so get will return null and version as -1, and this is returned to more threads simultaneously they all call prepareIndex but of coure only last document is saved. I cant pass -1 as version number into prepareIndex method, it just thow Exception from ES. Is there any way to check versions on indexing new documents?
