Subject Re: How to use search index while indexing
Date Tue, 02 Feb 2010 14:09:11 GMT
I'm not sure that I understand the question.  Can you not use a
searcher based on the reader returned by IndexWriter.getReader() to
determine if the doc is already in the index?

Or just use IndexWriter.updateDocument to save or replace as appropriate.
