I will have to try this one.  I have to admit the code sample above 
doesn't make sense yet, but I will re-read the indexing documentation 
and see if I can figure it out.

Unfortunately I am not skilled enough to implement this.  It is one 
thing to make patches that change interfaces slightly or fix small parts 
of code, it is an entirely different thing to understand the full code 
base and add a large new capability. :)

I wish I had time to learn the code that well, but I do not right now.  
Sorry. :(

Thanks for your help.
