Subject: SRU - can I do a lookup via ISBN?

I am an utter newbie to SRU and would be very grateful for your help.

I am trying to implement an application in which the user
          (a) first scans an ISBN from a book, then
          (b) does a lookup via SRU to get information from the Library of Congress (and thereby avoid manual entry).

I am using (for example)
          http://z3950.loc.gov<http://z3950.loc.gov>:7090/voyager?version=1.1&operation=searchRetrieve&query=isbn=9781449313944

and I am getting back:
          numberOfRecords:     0
          diagnostic:       message:                      Unsupported index
                                              detail:              isbn

However, if I get the Explain record, it says
          <index id=“7”>
                      <title>isbn</title>
                      <map><name set=“bath”>isbn</name></map>
          </index>

So I would have thought that what I attempted to do was legal.

[1] What am I missing here?
[2] How can I do an ISBN lookup?

Thank you for your help.
