Mnesia -- "equals ignore case" equivalent?

[Steve Davis]

Hi,

I can't see any advice previously offered for the best way to query a
(large) mnesia table with a query comparable to "equals ignore case".

My first thought is to storing an indexed lower or upper "case"
version of the data in an additional field, but with nearly 20 million
records that doesn't seem very attractive.

TIA for any thoughts,

Regards,
Steve
