I cannot get Rushmore to use an index for a filtered SQL SELECT statement.
The result is always:
Using index c:\xx\xxdb\pagei.cdx tag _deleted to rushmore optimize table opendir
Rushmore optimization level for table opendir: partial

I've looked at the index in the .CDX file being used and it matches my parameter.
Here's some info about what I'm doing.
I'm missing something, but what?
Are my non-structural indexes a problem for Rushmore?
I'm using VFP9 SP1.

Thanks,
Howard
