I got curious and did a little experiment: the result for super search for reaped nodes doesn't return reaped nodes if words only appear in its reaped body, but it does return reaped nodes if the words searched for appear in their title, and your search includes searching in titles (the default).

For example, super search for "mod_perl" lists mod_perl 1.0 or 2.0 but not its reaped dupe modperl 1.0 or 2.0, where the word only appears in its body; but searching for "modperl" still lists the reaped node, where that word appears in the title.

That ain't right. IMO reaped nodes no longer actually exist, they're only shadows of old nodes. They only remain in the database for archiving purposes, in order not to falsify history (too much). They serve no other practical purpose, and IMO they should never be listed in a result in a Super Search. They should be suppressed.
