The example I sent you uses an external structure we call the "facet
map" to look up clusters on the fly[1]. It is an addition to the
Lucene index that can be updated at reasonably little overhead. -
Which still might be too much for a desktop box of course.

Well; I suggest showing results like in that link :-)

Keep a flat list of all results that can then be refined by clicking
on the clusters.
