You've neatly summed up the reason I say it is difficult.

Trying: C-u G G <RET>
Query: 'Subject:#queries'
or
Query: Subject:#queries

Either way produces:
Invalid read syntax: "#"

Query: Subject:.*queries
Invalid read syntax: "."

Even:
Query: ^Subject: example queries for nnir
or 
Query: Subject: example queries for nnir
with and without single quotes
Wrong type argument: listp, example

Trying to use the ";" operator (even though it would leave a gaping
whole for false hits): 
Query: Subject:;queries 
End of file during parsing

All the above leave room for false hits without the "^".  

I think this points up the weakness I mentioned.  And a good reason
why it would be nice if RE were usable in the queries of glimpse.

It appears that freeWAIS get around this problem neatly by use of
`fields' as you've described.
