The tools apropos and whatis can be used to quickly search for man pages if you don't know exactly what you are looking for. Unfortunately these tools do not work with our man pages as they rely on a separate database being updated. Our man pages aren't included in this database since we rely on $PATH rather than changing the system configuration. Doing it this way was an explicit choice as the system man configuration doesn't have a simple extension mechanism, and the only downside seem to be this very bug.
