I'm not handling a salary right now. But it looks like I should. I will try to do something about it.

Just a note. To have the search enabled on a salary, values have to be normalised to something, dollars sound good to me.

As for the keyword. This is something probably HN crew could decide on. In my opinion isn't needed as long salary is in first row with $xxx or $xxx-$xxx format. But since many people seems to be interested here. Maybe would be good idea to mention something about salary in the thread description.
