i was saying in order to use Rushmore there needs to be an index on the where-clause
from the help file:

Rushmore Query Optimization technology is a data access technique that uses standard Visual FoxPro indexes to optimize access to data. You can use Rushmore with any Visual FoxPro index, including FoxPro 1.x (.idx) indexes, compact (.idx) indexes, and compound (.cdx) indexes.

i was not talking about the order of the cursor
