Shawn Heisey updated SOLR-5670:
-------------------------------

    Attachment: SOLR-5670.patch

>From a design perspective, I can't claim to know whether this is an acceptable 
>patch or not.  Consistency in configs across multiple users and multiple 
>versions does have some value, which is a very minor argument against this 
>change.

Is there any benchmark data? If docValues provides better performance for 
_version_ than indexed when it is used for its intended purpose, it might be 
worth changing the example config ... but people should know that if they *do* 
change the config on this field, they will have to completely reindex.

This patch is functionally identical to the previous one, it just modifies an 
error message.  I didn't check to see what branch Per's patch was created on, 
but it did apply cleanly to branch_4x.  This patch is against that branch.

> _version_ either indexed OR docvalue

> As far as I can see there is no good reason to require that "_version_" field 
> has to be indexed if it is docvalued. So I guess it will be ok with a rule 
> saying "_version_ has to be either indexed or docvalue (allowed to be both)".
