Question

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?

Answer 1

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

Answer 2

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! =)
