You should use both closed and open questions. You should use a closed question because if you're only looking for
A yes or no answer and don't want a long exact answer. You could also used open questions to find the exact answer.
A Google search tips are good. Because if you're searching for a person but there are other people with that name then you can use a minus (-) to get rid of something in a search. Or you can add words like sam adams HISTORY and it will search for history.
