How more helpful could I possibly be?
The question is how to make the thing not case sensitive.
The answer is that it’s really not case sensitive in the first place.
Really.
Honest to god, no fooling, it’s *not* case sensitive.
If you think it is, then please, prove me wrong. Show me an example. Then I’ll really delve into it and try to solve your problem.
Really.
But at the moment, nobody can answer your question, because the question itself is invalid. You can’t even make the search case sensitive in the first place, without quite a lot of effort. So the easy answer would be don’t put in that effort to make it case sensitive.
What more do you want? Blood?
