re-indexing via source and scan 'search' works nicely. Be carefully when ditching mongodb as you won't get the document immediately after indexing (real time latency of every search solution). Of course you can work around this via calling expensive refresh (not recommended!) or via using the real time version information: set the version and when indexing fails due to a version conflict: 1. search to get the latest doc 2. try to index again (until success) On May 30, 3:03 am, Karma [akmal...@gmail.com](mailto:akmal...@gmail.com) wrote: > i'm interested in using ES as primary store and looking to ditch > mongodb, my question regardless roadmap and stabilty towards 1.0, when > something bad happens, would i be able to re-index by using data from > ES \_source ? ---

Thanks, after hours of creating and playing with golang DB interface for ES as data store i came to conclusion, ES was never meant to replace a real DB. so i'm back to ES+Mongodb (with \_source disabled) On May 30, 9:20 pm, Karussell [tableyourt...@googlemail.com](mailto:tableyourt...@googlemail.com) wrote: > re-indexing via source and scan 'search' works nicely. > > Be carefully when ditching mongodb as you won't get the document > immediately after indexing (real time latency of every search > solution). > Of course you can work around this via calling expensive refresh (not > recommended!) or via using the real time version information: set the > version and when indexing fails due to a version conflict: > > 1. search to get the latest doc > 2. try to index again (until success) > > On May 30, 3:03 am, Karma [akmal...@gmail.com](mailto:akmal...@gmail.com) wrote: > > > i'm interested in using ES as primary store and looking to ditch > > mongodb, my question regardless roadmap and stabilty towards 1.0, when > > something bad happens, would i be able to re-index by using data from > > ES \_source ? ---

That's indeed the case, but I'm using it as DB. So what were your problems? ---
