We have created a content source and we would like it to be excluded from the SharePoint search results.
I know one way would be to use Query Rules and exclude the content sources using following query
However I am assuming that it must be pulling all the search results initially and trimming them based on the Query, which would have some performance impact.
Do we have any other way of achieving this other then Query Rules or Crawl Rules?
Appreciate your help on this.
