Using search refining with carrot2?

Hi,

I am trying to suggest refine searches for my search. For example, if
a search turned out too many searches, it would list a number of
document title subsequences that occurred frequently in the hits of
the previous search, as possible candidates for refining the search.
This is somewhat similar to search clustering I hope - which is
already implemented by carrot2 in Nutch. Is carrot2 and search
clustering the right approach in this case?

I also tried to include carrot2 in my application but am getting the
following error:
java.lang.AbstractMethodError:
org.apache.nutch.clustering.carrot2.Clusterer.clusterHits([Lorg/apache/nutch/search/hit/HitDetails;[Ljava/lang/String;)[Lorg/apache/nutch/clustering/HitsCluster;
        at org.apache.jsp.search_005fnew_jsp._jspService(org.apache.jsp.search_005fnew_jsp:539)
Does anyone have an idea as to the cause of the error?

Thanks :)

CW

Hey,
there is a interesting discussion in the lucene mailing list about a  
similar theme.

I'm not sure if Dawid has subscribed the nutch user list also, so you  
may you can catch and him in the carrot mailing list.
