I've been having the same problem for months. All of the problems have been with books I bought on Amazon. Here's an example:
calibre, version 7.26.0
ERROR: No matches found: <p>Failed to find any books that match your search. Try making the search <b>less specific</b>. For example, use only the author's last name and a single distinctive word from the title.<p>To see the full log, click "Show details".
