Quoting of parentheses in text filters, single character wildcard

I often use text filters where I have strings like "xxabc(22)_cde" in all kinds of different combinations. Searching in these strings is a pain for me.

Take for example xxabc(20)_dd_ffj(22)_bla. I want a possibility to match for the j(22). The way to do this seems to be "*j(22)". In principle this is fine, but you cannot do the nice stuff like "*(j or c)(22)" with this which is really annoying.

To get rid of these issues, please introduce a simple \( or another quoting mechanism to match the literal (, of course also the corresponding \). In the beginning I thought "(" would do the trick but it doesn't, *j"("20")" matches the above example.

In addition, a wildcard which matches exactly one character would be great. How about the ? together with \? for quoting...
