Re: clarification on using docvalues for sorting

[Alessandro Benedetti <ab...@apache.org>]

This is a recurrent question,
according to my knowledge docValues are not supported for analyzed fields (
even if the analysis is simply not tokenizing but only lowercasing).
At the moment as Erick suggested I encourage you to do the lowercasing
before the indexing phase, when you supply your data to solr.

A contribution for docValues supporting single token tokenized  analyzers
would be more than welcome.

Cheers
