How to remove constant indexing of node_modules from PhpStorm?

Question

phpstorm

There is a project, a large one, a hodgepodge of subprojects, it has 4 large node_modules folders in 4 places.
All of them are marked as excluded .
The problem is that the storm, despite the excluded, starts indexing them every 3-10 minutes and indexes them for about 2 minutes. Terribly annoying.
Storm 2016.2.
Why does it index these folders? How can I prevent him from doing this?

Answer 1

CMD+,(settings) -> Editor -> File Types -> bottom:
You need to add, separated by a semicolon:
node_modules;
