Download Metadata Search Fail

[ErylFlynn]

So trying to understand better why it fails in some cases, despite being able to find it on Amazon, searching Google and more. Below is an example of the output from the failure. I know it works for other titles but I have many that do not work. Want to learn how I can make changes to get it to work more often.

Running identify query with parameters:
{'title': 'Dark Peace', 'authors': ['J.N. Chaney', 'M.F. Lerma'], 'identifiers': {'mobi-asin': 'B0BMT47F7P'}, 'timeout': 30}

Works for me. (I updated comments in my Dark Peace)
Using W10 Calibre 6.17

Running Linux myself, what information did you have in the author, title, and the ID fields?

[DNSB]

Generally, I find removing all the extra crap(*) from the title leaving just the title and making sure the Amazon ID (ASIN) is correct makes download Amazon's metadata a lot more reliable. Even then, Amazon seems to have cranked their DoS settings up to the point that doing more than 3 metadata searches rapidly will trigger a lockout returning no data for 5 minutes or so.

* I've never understood why Amazon's love for having the title, subtitle, series info and even "A Novel" in the title is useful. The last record holder also included most of the first paragraph of the blurb in the "title".

That ASIN (ASIN: 'B0BLCZGQ8L' is good

[ErylFlynn]

So no matter what I do it doesn't work. I verified some I downloaded before and it finds the titles. No idea why it won't find it.

Title: Dark Peace
Author: J.N. Chaney & M.F. Lerma (Also just J.N. Chaney)
ID: ASIN:B0BMT47F7P

I find that sometimes there is too much information for the Search.

Delete everything but the ASIN and try again.
Also ASIN:B0BMT47F7P might not work, you might have to change it to amazon:B0BMT47F7P (I think there is a setting for which prefix is used)

I have had quite a few books where this has happened and once I strip it down to a single search criteria, usually the amazon: or isbn:, the book is always found.

I tried and no luck so I cheated, downloaded a few other search plugins, one the Barnes and Noble and got a hit. Amazon and Google ones are too flaky in my experience they fail almost as often as they work.
