Id is not required for a Document. The search service can automatically create an identifier

[marcosvidolin]

Setting the document identifer is optional. If omitted, the search service will create an identifier.

Any updates on this ? This would block us.

I'd argue that setting ID is rather useful. Could you explain your scenario a little?

Also, if you really don't want a meaningful id then you can work around by not annotating any field with @DocumentId and passing a UUID while creating document. e.g.

Document myDoc = doco.toDocument(myEntity, "some-random-id-here");

Yes, the uuid approach is sufficient. What I wasn't sure of is whether there is a way to specify document id (without requiring an annotation).
