Subject Re: Removing Index

OK, that makes sense.  However my main question is how do I recover  
from a corrupt search index?  The automatic repair that seems to kick  
in on a restart notifies me that the index cannot be repaired.  It  
seems like a DB backup is not enough, and I also have to back up my  
file-based search indexes.  This seems bad, as it will be nearly  
impossible to take these two backup snapshots of two persistent  
stores in the same state.
