As someone with decades of search engine experience, it's mainly knowing key words and exact phrases to use as well as excludes to filter out garbage. It's a bit hard to teach/explain in a single post, but if you search basted turkey and get results of "turkey baster", then quote the key phrase "basted turkey" -shopping -sale -price, try and remove results from shopping websites with excludes. Understand most search engines will drop most 1-3 letter words from your search. Like searching for 'fire in the house' will only look for results most relevant to the words fire and house, because 'in' and 'the' are just common everywhere. So if you want that exact phrase, then quote it. Searching used to be something you had to learn how to do.
