Unless you want to write special code to change how Solr works, you
cannot pick and choose to apply synonyms to some documents but not
others.  The synonyms are always going to apply.  The synonyms you have
chosen will cause this match to happen.

You could instead use this format in your synonyms file for a one-way
translation, but then you would not be able to do the search for the
full text and match documents where "UVA" is actually used to mean the
university:

university of virginia => uva

Multi-word synonyms don't work properly unless the 'sow' parameter is
set to false.  This is the default setting since 7.0.

Thanks,
Shawn
