> "Why Isn't Sorting Working on my Text Fields?"
>
> Lucene Sorting requires that the field you want to sort on be indexed, but it
> cannot
> contain more then one "token" per document. Most Analyzers used on Text
> fields result
> in more then one token, so the simplest thing to do is to use copyField to
> index a second
> version of your field using the StrField class.
>
> If you need to do some processing on the field value using TokenFilters, you
> can also use
> the KeywordTokenizer, see the Solr example schema for more information.
> Sort on text fields does not work when there are capital alphabets and/or
> spaces
