Search facility?

I only use menuconfig and often times, it's difficult to find a
particular option I'm looking for.

Like the wiki page tells you where to look, so I look there, and the
option isn't there while others shown on the wiki page are --- very
likely using a different kernel version.  Now where is the option I need
to enable?  A tedious search begins ...

Is there a good way to find where options are?
