Subject Re: Incremental Indexing.
Date Tue, 09 Sep 2008 01:06:18 GMT
Hi Jang,

I've been working on Tag Index to address this issue.  It seems like a
popular feature and I have not had time to fully implement it yet.
http://issues.apache.org/jira/browse/LUCENE-1292  To be technical it
handles UN_TOKENIZED fields (did this name change now?) and some
specialized things to allow updating of parts of the inverted index.
If you're interested in working on it, feel free to let me know.

Cheers,
Jason
