This is not possible without a major re-structuring of Lucene. This has been discussed here before. Perhaps this should be in the FAQ. > b)There is no way to update just a field in a document,you > need to update the entire document, so a field update will be > good,may be this is hard to do.

This has also been discussed on the mailing lists, but not put into a published document. Hopefully most users should not need to know the details of the index format. However, it still should probably be documented.
