Subject Re: do i need a key if not going to query by key or update the document

No, you don't need a key for append-only usage.

Lucene itself doesn't care if you have a unique key per document, and
in fact it's very costly, especially if your documents are otherwise
tiny, to add one if you don't really need it.
