Surely basic common sense (as well as the Emacs manual) should tell a
user to try that. Anyway, let's move on...

I suspect it is a literal search.

it looks like "," acts as OR. So you are searching for "next-line" OR
"previous-line and goal-column". The advertized way to do an OR is to
specify "with subject containing" option multiple times. These seem to
give equivalent results.

There is a fancier search at,
but it does not work, since it needs "Hyper Estraier" support to be
activated and I do not know how to do that.

I'm not sure how useful it is, given that G**gle searches of work, and that is also searchable.
