content: What boolean operators do you use in search engines for getting more accurate results? As it's becoming more and more difficult to get the search results you actually want, I'm thinking about brushing up on my boolean search skills. The only ones I've ever used are putting a search in quotations " which keeps the words all included in the search, and putting a minus - in front of words to exclude from my search. Any other suggestions for how to really narrow down and optimize searches? Which boolean operators do you use?
