When searching Google, it often helps to limit your results to sites with specific domains. Include the phrase site:edu, or site:gov, or site:org after your search terms to get results from education, government, or organization sites. The examples below also use quotation marks to search by phrase instead of by individual word.
"artificial intelligence" site:edu
"black lives matter" site:org
"solar power" site:gov
Also consider searching Google Scholar. This is the part of Google that searches only scholarly literature. It searches university websites, open access repositories, and others.
