How to exclude/hide specific directories/folders from search in Atom Editor, per project


I have a directory with a bunch of Bootstrap versions in it, and every time I search my project for a Boostrap-related class name, I get a list with all the hits from my Bootstrap versions. I need to know how to exclude this directory from searches. I do not want to do this globally, and I’m not looking to use the search/pattern field in the ‘find’ panel (unless this field can get populated from a config file in the project). I need a solution that will persist every time I open this specific project in the future. Would this configuration be in .editorconfig or config.cson?

I searched for this solution elsewhere, but there’s a lot of noise in the threads related to my question, so it’s hard to identify the correct/best solution.
