We did some experimenting with manual searches and indexes today.  Standard
Koha seems to deliver all the 6xx fields indexed with all subfields, like this:

melm 650        Subject,Subject:p

We tried adding Subject:w as a setting, and reindexed.  That didn't make any
difference -- searching either 

su,phr: College teachers United States Periodicals

or

su: College teachers United States Periodicals

does not get any results.  I took a look at the way the non-XSLT search works,
and it's rather questionable:

su: College teachers and su: United States and su: Periodicals

This works and gets results, but it doesn't limit the results to records with
that as the entire subject entry "College teachers United States Periodicals"
in different subfields.  Rather, it's finding titles with a subject subfield of
College Teachers and perhaps another subject subfield in a different 6xx of
United States, etc.  Is that the best approach?  Isn't there any way to say
only search for this entire string in one 6xx field?

I haven't tried any code change yet with XSLT -- I want to understand how the
search works first.
