What are some tips and tricks to help in doing online research about a particular topic?

This is one of my goals of the year - to better myself at doing online research. I wish to be able to get more precise (?) results for what I am searching. Idk if I'm making myself clear here but I'd greatly appreciate any tips that you may have for me. Thanks in advance!

Edit: As pointed out in responses so far, my issue lies in not knowing how to properly ask the internet the question which I want answered. It's mostly a discussion about precise legal point that I seek in a judgement or academic article.
