FYI, your posts were waiting for mod approval. Hopefully you have enough posts now to not have that problem anymore.
"how the old grace goes" is a substring of "care not how the old grace goes", but that shouldn't be a problem.
I'm not able to replicate the problem. I can have either of those two stories in library already and then download the other by URL with "Search by Title/Author(s)" on and they don't conflict.
When you have the "Search by Title/Author(s) for If Story Already Exists?" option checked FFF looks for existing books with the same title and author by using Calibre's
db.find_identical_books() method(
FFF src).
I don't know why you are seeing that. I can force it to happen if I use
replace_metadata to force two different stories to have identical titles, but not just a substring. Or if I change the story name in library to match first.
db.find_identical_books() does 'fuzzy' title search, but unless there are Calibre settings for it or language setting differences, I don't know why we would get different results. Calibre code suggests the 'fuzzy' part refers to punctuation and whitespace differences.
If you run into it again, I would suggest one or more of:
- Use the No then Yes buttons on the matching title/auth dialogs to download anyway. Then future updates will match by story URL.
- Use 'Add Always' mode when downloading the second story.
- Uncheck the "Search by Title/Author(s)" option
- Use replace_metadata to change the title of one or the other, eg "how the old grace goes - Naruto".
