Well, I spoke to soon on the it all works front.  So, it's been reindexed and 
appears to be working properly now.  I guess I'll keep an eye on it for a 
while.  I didn't get your query suggestion in time, so hopefully I grabbed the 
right binary file..though it did seem to disappear after the reindex, so I 
think it's likely the correct one.  Definitely got the correct second one.
