Answer 1

Have a look at this: http://sujitpal.blogspot.com/2009/02/summarization-with-lucene.html

The class in this page hascomputeTopTermQuery method which you should be easily able to retrofit for going over multiple indexes.

Answer 2

A very simple way would be to use Luke. On the 'Overview' tab, there is a 'Show top terms' button that can be used for what you need.
