Using closed and open questions is important. It's important because if you only use closed questions then you can't go into any depth on why or how. Its also important to just use open questions because then you can get some quick answers if you used closed when it's necessary. That's why you should use both open and closed questions.
Using Google search tips is important. Google search tips are just shortcuts that can make searching quicker and simpler for example if you need to define a word most people would search something like the definition of tools. If instead you just search Definition:tools then your results will be more accurate. Also if you want to search something that has two common known names you could just search puppies OR pups that makes your search results more accurate as well.
