This question is probably more appropriate for the dev list than the
solr-user list, especially since it has more to do with Lucene than Solr.

If the javadocs for the classes you want to use are not providing enough
info, then you may be able to learn more by looking into the tests
included in the Lucene source code that use the framework classes you'd
like to try.
