Case sensitive search: Which search engines?

Which major search engines offer a case sensitive search (distinguish
the capital letters in the search keywords)? As far as I know, Google
does not -- what about the other engines?

Don't know, but didn't Google used to do so?
Seems I remember search instructions suggesting when and whennot to use caps.

I think it used to be that in many search engines, a lower case search
term would be case insensitive, but upper case not.

So lower case should catch all, capitals and lower case combined would
be case sensitive.

Don't know if this is still the case, but some trial and error testing
would probably be the way to find out.

A case sensitive search would be really difficult for an engine maker
to do, simply because of all the possible combinations of letters that
go in to making a word.

Typically, they have a lexicon style database and a flag indicating
if it's all lower case or "mixed case" (one or more letters is uppercase)

This allows them to represent words with numbers and index them faster.
