It doesn’t. The statement says you’ll need to use the regular plexmatch hinting approach to tell Plex what show/season/episodes each of those files are because it won’t recognize them based on their file names.
The support article from which you’re quoting describes how to use .plexmatch files to give the scanner hints on how to match certain files.
Initially those files focused on hints for individual files.
With PMS 1.30.0, Plex introduced an option to specify a pattern to specify where in a file name to find information for season/episode etc. – those patterns also support an option to specify see style notations.
Let’s take the example from the support article.
You’ve got your files organized like this, with 24 episodes of season 1.
TV Shows
Show Title (2021)
Season 01
Show Title 101.mp4
Show Title 102.mp4
...
Show Title 124.mp4
You’ll place a .plexmatch file in the Season 01 folder. This file should contain the following information (I’ll ignore the comments from the example to make it a bit more lean):
Title: Show Title
Year: 2021
Season: 1
Pattern: Show Title {see}.mp4
Assuming your files are in proper order, you shouldn’t need any of the additional information in the curly brackets.
Ok, I already tried exactly that, BUT I used an asterisk, like its explained and shown in the article.
But *-{see}.mkv doesn’t work, only the exact filename works. Not quite what I would understand under pattern matching, and the examples also shows different, or I’m still not understanding them.
EDIT: Alright, * only works trailing after the {see} term.
