Taking this to java-dev: Since this is such a common issue, would it
be feasible for Lucene to have some sort of capability to be told
what field is the unique one and automatically update (delete, and
add) a document added with a duplicate of a unique field? This
would probably require that Lucene enforce this uniqueness during an
add, though, right?

Lucene has no notion of a "unique field" ... you will need to delete
the old record ... but you don't neccessarily need to delete it first.
