: Calling "getVal()" on a DocTermsIndexDocValues does some really weird stuff

Your TextField is being analyzed in some way you haven't clarified, and
the DocTermsIndexDocValues you get contains the details of each term in
that TextField

Based on your initial goal, you are most certainly going about this in a

You are going to be *MUCH* happier (both in terms of effort, and in terms
of performance) if instead of writing a custom function to parse strings
at query time when sorting, you implement the parsing logic when indexing
the doc and index it up front as a date field that you can sort on.
I would suggest something like CloneFieldUpdateProcessorFactory +
RegexReplaceProcessorFactory could save you the work of needing to
implement any custom logic -- but as Jack pointed out in SOLR-4864 it
doesn't currently allow you to do capture group replacements (but maybe
you could contribute a patch to fix that instead of needing to write
completely custom code for yourself)
Of maybe, as is, you could use RegexReplaceProcessorFactory to throw away
non digits - and then use ParseDateFieldUpdateProcessorFactory to get what
you want? (I'm not certain - i haven't played with
ParseDateFieldUpdateProcessorFactory much)
