Sorry, but I don't see a mechanism where this can happen.  SRW searches
can't be sent, unchanged, to multiple servers for exactly the same reasons
that it doesn't work in classic Z39.50.  Different servers provide different
access points to their data.  In classic Z39.50, that means different
attribute combinations.  In SRW, that means different indexes.
