Thanks for the response (and sorry for the excessive duplicate posting to the list, that obviously wasn't on purpose).
I should have explicitly asked this, but one specific thing I wondered was whether LUCENE-3065 would make any difference in my example program (I haven't had time to test it yet) In the meantime I have gone through the motions to rebuild my doc from whole cloth and I'm reasonably sure it is working me :-) Thanks! -----Original Message----- From: Ian Lea [mailto:ian....@gmail.com] Sent: Thursday, May 10, 2012 1:20 AM To: java-user@lucene.apache.org Subject: Re: update/re-add an existing document with numeric fields You can't selectively update fields in docs read from an index, in old or current versions of lucene. I think there are some ideas floating around but nothing usable today as far as I know. You'll need to rebuild the whole doc before passing it to writer.updateDocument(). -- Ian.
