Nextant and bookmarks

Dear Nextcloud users,
I got nextant working with tesseract and it’s pretty nice for searching text files and image files. I was hoping that I could search my bookmarks with it but none of my bookmarks come back from my search requests. Is that the currently expected behavior? Am I searching in the right part of the web page? (files > magnifier glass > field)?

I thought perhaps it only searches the bookmark comment field but it doesn’t do that either.
