Summary: Create new hash index for active string modification
Initial Comment:
Upon a search clause such as lower(...) or upper(...) it would probably be
beneficial to create an extra hash index to represent the new compared strings.
Next to this, I don't know if Monet already uses tricks such to directly quit
if lower(something) = 'HELLO', but this can be included.

Please explain what "active string modification" is and in which apparent
cases this would cause a problem.

Message:
I wonder now if it wouldn't be more interesting to make it by default
caseless, since this will allow all operations {upper, lower, none}, and
would only act as prefilter.
