About the only way to do this that I know of is to
index the data three times, once without any case
changing, once uppercased and once lowercased.
You'll have to watch your analyzer, probably making
up your own (easily done, see the synonym analyzer
in Lucene in Action).
Your example doesn't tell us anything, since the critical
information is the *analyzer* you use, both at query and
at index times. The analyzer is responsible for any
transformations, like case folding, tokenizing, etc.
But what is your use-case for needing both upper and
lower case comparisons? I have a hard time coming
up with a reason to do both that wouldn't be satisfied
by just a caseless search.
