Search error?

I sometimes need to be able to search for for example different variables in the code. There seems to be a small error in this search possibility, as it only returns the lines where the variables are being set, like "Variable Set %var to 0", but not the lines where the variables are being used, for instance if you set a command to be run only "If %var = 0" or something like that, the search for "%var" doesn't stop at that command. Anything to do about that?
