It shouldn't do, no. You'll start getting issues if you need to move
to multiple databases, or something else more complex, but for now you
should be fine.

If you use replace_document(), it will be indexed with the right
ID. To get a list of docids, probably the quickest thing is to write a
quick PHP script to check $db->get_document(docid) for all docids you
care about. $db->get_lastdocid() and $db->get_doccount() will help here.

Try $mset->get_docid().

$mset->get_document()->get_data() will return whatever you put in
there in the first place (using $doc->set_data()), so my guess is you
aren't putting anything there at all right now. For your application
you may not have a use for it.
