Use the minus sign ("-") before a keyword to eliminate results that include that word. For example:
Search for "site:URL keyword." For example:
Google Scholar, PubMed, and other websites can connect you to a lot of scholarly content. Google Scholar in particular is bigger than any single library database.
Many websites ask you to pay for full-text access, but you can get access for free through SMU Libraries. Either look up the article in Library Search or use the LibKey Nomad browser extension.
