Newbie with Carrot2?

[Bruno Mannina]

Dear all,

I use Solr 3.6.0 and I indexed some documents (around 12000).
Each documents contains a Abstract-en field (and some other fields).
Is it possible to use Carrot2 to create cluster (classes) with the 
Abstract-en field?

What must I configure in the schema.xml ? or in other files?

Sorry for my newbie question, but I found only documentation for 
Workbench tool.
