Regex exclude syncthing conflicts

I want to:

Exclude all syncthing conflict files

I’ve tried:

And various combinations of that using *

But the sync conflict files still come up in search results.

What is the regex format please?

You fail to mention how the syncthing conflict files look like, and whether they’re in a given folder or spread across your entire vault.

And please examplify some of your attempts on patterns you’ve tried.

.*sync-conflict.*

example: changelog.sync-conflict-20240208-004657-YN4TSFS.md
