I don't have the source code for SRW, if you send it to me I could take a look.  

I'm not following the Lucene issue completely.  Maybe I don't have to, and all I need to do is change the getTermList code? Or maybe when I read the code it will make more sense?

I'm going to be leaving very soon, so if you don't hear back from me, we can continue this conversation next week?

Thank you!
Jose

The Lucene issue requires that the responsePosition be 1 instead of 10.
That means your seed term must be the first term in the response and
that you can't go backwards through the index.  That was the same
limitation in DSpace 1.4.

The getTermList() method in the SRWLuceneDatabase class needs to be
updated.  It should look like familiar DSpace code.  I just couldn't
figure out how to use the new API and couldn't find the equivalent
client code in the DSpace user interface.
