You need a reset method that calls the super reset to reset the parent
state and then reset your own state.
http://lucene.apache.org/core/4_0_0/core/org/apache/lucene/analysis/TokenStream.html#reset()
You probably don't have one, so only the parent state gets reset.

Ah! You're quoting full phrases. You weren't clear about that originally.
Thanks for the clarification.

Subject: Retrieving granular scores back from Lucene/SOLR
Hi,
I am looking to get a bit more information back from SOLR/Lucene
And to be more specific, most query parsers will have already separated the
terms and will call the analyzer with only one term at a time, so no term
recombination is possible for those parsed terms, at query time.

You still have the query parser's parsing before analysis to deal with, no
matter what magic you code in your analyzer.

Thanks, you answered the main question - 26 doesn't simply lop off the time
