I agree exalead help needs improvement. Thanks for starting to work on it. Why don't you put the help in a limited-access WIKI (multi-language, of course), and allow access, for example, to "feedback members" with a minimum number of contributions? That would save you a lot of work.....

Not only that, but the help need to be contexte sensitive. How about having a little "orange question mark" for every search option to display the hepl for that particular feature in an AJAX maneer (that is, by opening a subwindow with the help in it)
