You should use both open and closed questions because there are benefits of each answer. A benefit of closed questions are that you don't get too much unneeded information because the answers are usually only a few words. A benefit of open questions are getting a lot of information and detail to the answer.
You should use Google Search tips because it can be helpful with a question you might have. For example if wanted to define something it will give you the definition of what you typed in. If I typed in ¨confused¨ it will say something like ¨a person who is unable to think clearly.¨
