OC,

To my knowledge, FrontBase does not support such thing. But I would not expect 
major speed gain unless your table have a very huge number of entries, in the 
100s of millions.

First make sure your indexes are kept in memory and uses READ_COMMITED.

You may have to add or adjust some index to be 2 keys (partitioning attribute 
and searched attribute) to help the lookup. The partitioning described 
basically does that...

If you have specific situation that takes unexpected time to execute, you may 
help by creating some multi key indices; querying multiple indexes and 
intersecting results is time consuming.
