I don't know how easy it would be to provide, but I offer this other
example of when a "raw" search option would be useful. There are 70 to 80
sequences that consist only of "1"s and "-1"s and I know no way to make
the search distinguish the two values, making it more difficult to find
such a sequence, and even more awkward to be sure such a sequence is
absent.

Best Regards,
Peter
