Search widget or shortcode ?

Hi,
I have just installed Search Everything and it almost does what I have been searching for via many failed alternatives. But, because the documentation I’ve found doesn’t identify how to produce a search page/shortcode (it seems to depend on the standard WP Search Widget), it doesn’t keep the search behind a login and therefore defeats the privacy intended by logging in.

Can you advise how to put the search box on a page please – I can then ensure searchers are logged in.
Many Thanks
Bob
PS Some search results are highlighted as expected but several display in a different font colour without highlighting – doesn’t concern me but thought you might want to know.
