If by UID you mean the internal, volatile, Lucene integer used to
identify docs, then, yes, it must be an integer. If by UID you mean
some application specific field set on your document, then it can be
whatever you want that uniquely identifies that doc. Just know
Lucene knows nothing about it being your UID.
