When the logical operator is used to combine keywords, a search engine will retrieve all results containing either keyword.
a. and
b. or
c. if
d. not?

OR! Because one OR the other (or both, as this is not an exclusive or) needs to be present in the search result.

Hi!

So, the logical operator which will retrieve all results which contain either keyword is going to be OR. 

Let's just do a little something to remember this...

So, the question says I need to find a logical operator which will retrieve all results containing either keyword. This means it'd have to show KeyWordExample1, OR, KeyWordExample2. 

Hopefully, this helps! =)
