I assume you can still use the Boolean "AND" operator which was always the way to ensure two terms were included in a Google search
I was a great user of the + operator added to the start of a single term but can see the logic of the change, [for whatever reason it's changed

] to include a specific phrase you use quotes even when the phrase is one word long - not too difficult to conceptualize
I will be sorry to lose the - operator though "NOT" should still replace it
