The sha1/sha1base36 search of list=filearchive does not work, because the used database field contains more than the hash (also the file extension), but it is using a equals sign in the sql.

When using sha1base36 you can add the file extension and find that file, but a sha1 with file extension is invalid and all files are list (bug 27593).
