I know you can hint a fast full scan. I have run into cases lately where depending on circumstances Oracle will use an index, but use a sub-optimal type of index scan with dramatic differences in performances.

This is on 9.2. Any hints for forcing an 'index range scan'. Anything stronger than a 'hint'. Something like 'do it because I said so'.

This only happens occasionaly, so Id just like to know if it exists for future reference.
