Ferret talk - Jan 2006 - Java Lucene compatibility?

I haven''t dug into this yet, but wanted to report it.  I''ve
built an
index with Java Lucene (1.9, from svn trunk) and then trying to  
search it with Ferret and getting this:

/usr/lib/ruby/site_ruby/1.8/ferret/index/term_buffer.rb:31:in `read'':

I''m using trunk of Ferret also.

I''ll work on building an index solely with Ferret and comparing with  
Java Lucene.
