I've had some experience with that. My main problem was that I had a limited vocabulary and
a large number of documents. It seems like solandra kept all my documents on the same row
for a given term. That means the documents don't get spread out throught the cluster and search
was painfully slow. We ended up rolling up our own solution and not using cassandra at all
for that purpose (althought we still use it for storage).
