if a tracker already provides an index on classes and properties,
a keyword index is a small overhead (especially with highly
optimised keyword indices such as Lucene).  The trick is to
find the sweet spot between indexing overhead and benefit
I guess.

Deciding which keyword query to send to which tracker is
tricky.  If trackers link to other trackers, keyword queries
could be routed along these links, but that wouldn't
guarantee web-wide completeness.

For smaller communities of users that maintain networks of
trackers the approach might be reasonably complete though.

Andreas.
