Yep. PerFieldAnalyzerWrapper seems to have solved my problem.

Thanks,

Subject: Re: Phrase search on NOT_ANALYZED content

I'm still struggling with your overall goal here, but...

It sounds like what you're looking for is an exact match
in some cases but not others? In which case you could
think about indexing the info: field in a second field and
adding a clause against *that* field for your phrase case.
PerFieldAnalyzerWrapper is your friend here <G>.
