I don't think you can. I gather that the Google text search algorithm
is word-based. It seems like you can't search for things that it
doesn't consider to be words. It has a pretty expansive notion of
what a word is (like "2a43" is a word, for example) but any non-word
characters are ignored (so, for example, "2a43$" returns the same hits
as "2a43").
