what "document based clustering" is?
This mostly means finding document which are "similar" in some way(s). The "similitude" is mostly in the eyes of the beholder. In such a world, a "cluster" would be a pile of document sharing something. As far as Lucene goes, a straightforward way of approaching this could be to use an entire document content to query an index. Lucene's result set could be construed as a "document cluster". Admittedly, this is ground zero of "document clustering", but here you go anyway :)
Here is an illustration:
