> This is a class I have found to be useful for analyzing small (in the 
> hundreds) collections of documents and  removing any duplicate content such 
> as standard disclaimers or repeated text in an exchange of  emails.
> This has applications in sampling query results to identify key phrases, 
> improving speed-reading of results with similar content (eg email 
> threads/forum messages) or just removing duplicated noise from a search index.
> To be more generally useful it needs to scale to millions of documents - in 
> which case an alternative implementation is required. See the notes in the 
> Javadocs for this class for more discussion on this
