It should trim a property if not highlighted.  For that matter it should
just highlight words based on metaname.

Without looking, it may be that the query parsing code is failing.  One
thing you might try is using a well formed query -- so instead of 

    username=andrew and year=2002 and DNA


    username=(andrew) and year=(2002) and swishdefault=(DNA)

A regular expression has to be used to break the query into groups by
metaname (so the highlighting code knows which words go with each metaname).

The script uses the "Parsed Words" header output from swish.  So you might
print that to stderr.  Also, there's some debugging at the end of
extract_query_match() that you can uncomment to see how it's parsing out
your query.  That also might give you an idea of what's going wrong.

I've been saying for months that that script could use a rewrite.

BTW -- you might also try using the -L limit setting for limiting by years
or a date range.
