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.

> 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)".
