Nutch vs Lucene
So Nutch uses (but doesn't enhance) Lucene? Or, does it enhance Lucene in its ability to operate in a distributed fashion?
Regards,
Terry
PS: I'm aware of Doug's involvement in both - which is partly why I'm puzzled.

Nutch is a robust, multi-threaded Java web crawler and a (distributed)
search engine.
Nutch uses Lucene to index web pages and search the resulting indices.
Doug Cutting is the padre of both Nutch and Lucene.

Nutch is built on top and around Lucene.
It lets you run a query against a cluster of 'search servers', for
instance, using custom code that you can see in Nutch's CVS.
