Solr should be act as the backend indexing server for Nutch instead of the
lucene index.
You have to patch the nutch at first.

Hi.
I'm confused by the UUID type comment. It's said that
/**
* Generates a UUID if val is either null, empty or "NEW".

* Otherwise it behaves much like a StrField but checks that the value

*
* @param val The value of the field
* @see org.ap
