Hi Carl,
Search isn't case sensitive however there are issues where it's matching isn't optimal, which will be addressed.
***UPDATE***
It appears that the Clibu search is indeed case insensitive already. So I think I've hit a bug.
I have an article with the words "MQ Native" in the title.

I just discovered today that Clibu's search is case sensitive. For improved usability, it should default to case insensitive searching. (I assume that the normal search options like case-sensitivity, whole word search, etc., will be added later.)
