How do I exclude a certain vendor in supply theme search

Hi there,


Is anyone able to help me to edit my search results to exclude a certain vendor from search results?

I have certain product form a ceratin vendor that I don't want coming up in any search results should someone search another product using the search bar on the site.

I have seen some code that can be changed to do this but the article has little context and does not say where the code must be changed.

Any help will be greatly appreciated.
