Not sure if this is a bug or is just not implemented.
I have many strict preferred word regex’s setup for show releases and Sonarr grabs and sends to the download client accordingly. However, once the episode/file is downloaded, Sonarr uses the filename to determine preferred words score instead of the release title it grabbed that file from.
To be specific:
As listed on nyaa.si, the release
[LostYears] Attack on Titan: The Final Season - Part 2 (WEB 1080p Hi10 AAC E-AC-3) [Dual-Audio] | Shingeki no Kyojin
contains the preferred words LostYears
and Dual Audio
with a preferred words score of 1000.
However, the filename for each episode is listed as
[LostYears] Attack on Titan - S04E17 (WEB 1080p Hi10 AAC E-AC-3)
only containing LostYears
as preferred words and with a score of 250.
Some releases contain several preferred words, putting them at the top of the search or RSS Sync but do not contain any preferred words in their filename, causing Sonarr to download but never import said file due to that file not being of a higher preferred words score than the current file.
