Answer
Yes, but the built-in Document Search full-text feature only works for documents that are actually stored INSIDE the database itself — documents stored in an external file-based repository location aren't covered by that built-in search feature at all. This is an important tradeoff to weigh against moving large document volumes to external storage for size/backup-performance reasons, since doing so comes at the direct cost of losing built-in full-text document search for those externally-stored documents.
