I was thinking of 3 new criteria for duplicate file finding. This are criteria that are a 'second pass'. So first there is a duplicate check on the normal way. After that, if results are found, a new check is done to match any of these criteria

1. Has same file type
true false no-check
2. Has a max-difference in pages of:
3. Has a max-difference in size of:

If you have this list (test same author, same title):
And Then There Were None - Agatha Christie - EPUB - 0.1MB - 180 pages
And Then There Were None - Agatha Christie - EPUB - 0.1MB - 199 pages
And Then There Were None - Agatha Christie - EPUB - 0.5MB - 180 pages
And Then There Were None - Agatha Christie - PDF - 0.1MB - 180 pages
Anna Karenina - Graf Leo Tolstoy - PDF - 0.1MB - 180 pages
Anna Karenina - Graf Leo Tolstoy - PDF - 0.2MB - 180 pages

Results would be:

Spoiler:

The advantage would be that you could filter for example books with great page or size difference, there books are likely to be no duplicate.
Books with just 1 or 2 pages difference is more likely to be duplicate.
The advantage of option 1 would be in case you have books with different file-formats, If you should only have books with different formats in your view, it is easy to perform a merge-action on it.

All options should be optional because your current search should have to work like it does now of course.
