Search for books with COMMENT

[PhilippKammann]

Describe your suggested feature

Some epubs have issues that Komga explains in a COMMENT (example below). It would be nice if if you could search for these books to know which you need to fix up.
For example with something like "comment:true" similair to "deleted:true"
