I did some testing with nutch searching over a solr index. Like Chris
said "compatible schema" are the only important point on this issue.

To put it in other words, nutch uses by default <field name="content"/>
to search and returns some fields by default. So if you are not keen to
write your own nutch plugin for your custom solr schema, just make sure
that you use the field name="content" to store your main text. You can
further enhance the integration by using the "nutch" names for
"important" fields. 

Further I have <field name="url"/> in my schema and it is the only field
that I see in the response of nutch.

sh bin/nutch org.apache.nutch.searcher.NutchBean presidencia

 1 null//2006/209/disposition/20246-a.html

 2 null//2006/209/disposition/20034-a.html

This is good enough for my client and me since I can transform that
afterward. :)

Thanks Chris and Otis for your feedback.
