Re: Kertana and searching for a file, or for key words in a file
Everything search can search file contents, but unlike Windows Search the Everything does not index file contents, so searching on file content alone, unless you also combine it with a suspected file name/wildcard, will be painfully slow compared to a straight Everything search. See: https://voidtools.com/faq/#does_everything_search_file_contents
Sharon, hit the WinKey then enter "Cortana" sans quotation marks. You should get the "Cortana & Search" settings returned, probably as the first item. Once you've gained focus on that then hit enter to open it. In Version 1607 there is a toggle (checkbox) for "Search Online & include web results" which you will want to toggle off if you wish to avoid having web results in your Windows Cortana searches.
Presenting the willfully ignorant with facts is the very definition of casting pearls before swine.
