Generally speaking, search results contain EXACTLY the information that
was submitted for indexing, assuming that the value was stored.  In
newer versions, docValues can be used instead of stored in order to have
the field appear in results.  Index analysis only affects the search
index, what happens there will never show up in search results.  This is
a fundamental aspect of Solr's operation.

You *can* use a custom UpdateRequestProcessor.  For what you're talking
about, that would probably be a custom processor that you write yourself
and inject into Solr as a plugin.  Update processors are executed on the
indexed data, *before* it reaches the actual indexing part of Solr ...
so stored/docValues data is also affected.
