Hi All,

I created this script [script source](https://gist.github.com/pjanzen/23c82407b729aaa58911995db918f323) and in it self it is working fine but due to using parallel\_bulk updates I am getting version conflict errors. I cannot get clear from the documentation what option I must set to get those failures to retry.

The goal of this script is to read index A, update index B and delete the records from index A, as I am doing the delete first I cannot got back on those records and as I do not have the orginal id in the update records I cannot pop him out either.

So hopefully someone can help me with either set a retry option or with the later question.

Thanks,  
Paul.
