Lucene index verifier

[Lance Norskog]

(Sorry, my Lucene java-user access is wonky.)
 
I would like to verify that my snapshots are not corrupt before I enable
them.
 
What is the simplest program to verify that a Lucene index is not corrupt?
 
Or, what is a Solr query that will verify that there is no corruption? With
the minimum amount of time?
 
Thanks,
