 Nutch has two indexing/searching backends - the one that is configured
 by default uses plain Lucene, and it does not support faceting. The
 other backend uses Solr, and then of course it supports faceting and all
 other Solr features.

 So in your case you need to switch to use Solr indexing (and searching).

Although I haven't tried it, maybe you can build a faceting plugin for nutch
using  http://sna-projects.com/bobo .
