1. Starting a search on Genesis I was offered many options that were missing a space:

2. I then did a search on Genesis2 in which Logos (un)helpfully corrected by adding the space. Usually a correct response.
3. So I added quote marks so that Logos would not autocorrect and found that the problem is that superscripts were not treated as superscripts.

What makes me think that this may be a programming problem is that the quotation in the Search box has the error but the actual text opened by a click does not have the error.
