Bit-mapped index documentation/support?

Where is there documentation (including basics like syntax) on BMI's? Haven't located any on the 7.3 CD disk. Seen the Oracle "White Paper" but that's mostly market-talk.

Also--do any design tools support/use BMI's? Like ER-Win?

Also--can anyone confirm the claim that BMI's actually deliver order-of-magnitude performance gains on queries?

Thanks.
