I created a new search page on the global search center. I edited the search result webpart and selected a custom result source. The custom result source is using this query:
{SearchTerms} Path:http://archive.myCompany.com
When I go to my new search page I see there alot of results already. I didnt add some keyword or press on enter!! I would like to have 0 results by default. After I add some keyword and press on enter, I would like to show search results.
