Subject Re: Getting the frequencies by corresponding order of documents were indexed
Date Fri, 11 May 2012 11:22:12 GMT
Can't spot anything obviously wrong in your code and what you are
trying to do should work.  Are you positive that what you think is the
second doc is really being added second?  You only show one doc being
added.  Are there already 7 docs in the index before you start?
