Don't pin me down on the details but AFAIK there are many other
significant differences between Nutch and Solr. At a high level this
is my understanding:
Solr is really meant for enterprise search where there is more
structured data and it makes sense to enforce a schema on at least
part of the index, so you can do better sorting (e.g. by date or part
number). I also believe it has a more controlled way of dealing with
caches, warming etc.
Nutch has a rich set of plugins that is geared to analyzing
unstructured data including office documents etc. There is a patch
for SOLR to achieve this as well but as far as I can see it is not
yet in the main line.
But at a high level, if you want to use Solr for general web
indexing, you'll need a spider/crawler from some other place.

web your self, or with some other tool?
