As Teodor already pointed there is no non-ambiguous solution, or
at least, we don't know it.

I had thought about this before myself. Alas I have never had the time to
properly investigate implementing such a feature.

A & (B | (New + York))
Something like that?
Actually, I love that idea. Oleg, would it be possible to create a
tsquery operator that understands proximity? Or, how allowing a
predicate to the current '&' op, as in '&[dist<=1]' meaning "next
token follows with a max distance of 1". I imagine that it would
only be useful on unstripped tsvectors, but if the lexem position is
already stored ...
Would the proximity go in both directions? Or just forward? What about tokens
that come before? Just a thought.
