How do you approach researching a topic?

The more and more I learn, the more I find my self weak in researching. So how do you do it? If for example there is a topic I don't know about, how do you grasp the jargon, is there a tool to fetch jargon on a topic. Or how do you approach navigating your way through the mess of search engines, how do you find fairly biased content (not too much, preferably unbiased)? I know reading books is a good idea in this case, however not everything is in books or not in the way I can grasp.

Are there any machine learning tools that specialize in creating a report for things you need, I know of freelancers who do that thing.

How do you do it? What medium of knowledge has the most bandwidth of good information? Is it worth it to go the later pages in the search engines?

I know this is a broad question I am asking, I like to know your opinion and if you have some facts, book recommendations or anything that could be of help don't hesitate to share it.

Thanks for your consideration.
