No offense whatsoever. I think my longer reply paints a more accurate light
on what Lily means in terms of "SOLR for NoSQL", and it was your reaction
who triggered this additional explanation.

There are some initiatives in the context of Cassandra IIRC, as well as a
project which stores Lucene index files in HBase tables, but frankly they
seem more experimentation, and also I think the nature of how Lucene/SOLR
works + what HBase does on top of Hadoop FS somehow is in conflict with each
other. Too many layers of indirection will kill performance on every layer.

interface and possible area of improvement against a too-low level of
