Hi,

I guess what you are looking for is regexp search.

You can use incremental regexp search with C-M-s and enter regular
expression corresponding to your needs or use M-x occur again with
regexp to show all occurrences at once.

case-fold-search variable determines whether searches are case sensitive.
You can temporarily change its value in your current buffer with 
M-x set-variable ENTER case-fold-search ENTER nil ENTER

Foregoing will make search operations case sensitive

BTW, by default search is not case sensitive unless you type in mixed
case or uppercase and if you do that Emacs understands that you want 
to make case sensitive search.
