@bookrbt,
Attached is a little story made of images strung from top to bottom. The images were made from test data created by adding format-less "empty books" just now for this purpose with the Quarantine And Scrub add-on.
Q&S does "Series-Level" scrubbing, including Series consolidation and renaming, as well as validation of Series and Index via a web source.
There is a little "chicken and the egg" here. The "seed" is the example book that already had a valid Series. A validation of that Series took place, during which all 37 books within that Series were stored permanently within Q&S for future use. There is an image of that.
When the "egg" (the book with no Series) was scrubbed by Q&S, it matched the Author and Title to known combinations stored permanently when the "seed" was validated against a web source. It then changed the Index accordingly. It can also change the Title to the correct Title if the Index is identical to what the web source said, and the % similarity that is calculated is high enough.
The source of support and further information about Q&S is its User Guide and OP for the thread below.
