Hi Jörg, as I understand, even with external versioning its not possible to update a doc *without changing/not incrementing* the version number at all.
1. User A loads DOC123 with version 20 and locally starts editing critical fields 2. User B simply loads DOC123 to view/read only. A view counter will be incremented, so also the version number will be set to 21 (or something higher with external versioning, but not to 20 again) 3. User A tries to send the updates from (1) with version number 20 to ensure he has the current version and update will fail, cause version number has changed Thanks Joa -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
