No, IndexWriter enforces that the number of documents cannot go over IndexWriter.MAX_DOCS (which is a bit less than 2^31) and BaseCompositeReader computes the number of documents in a long variable and ensures it is less than 2^31, so you cannot have indexes that contain more than 2^31 documents.
Larger collections should be written to multiple shards and use TopDocs.merge to merge results.
