Using site: in Google can quickly narrow your results to get you what you need faster.
You can use site:.gov to find only websites ending in .gov.
You can also use site: to search within websites. Find the base URL of a site (commercialappeal.com, for example), then use site:commercialappeal.com and your search terms to search within the website The Commercial Appeal. This can be done with any website, not just newspapers.
To search courts & cases, select Case Law under the search bar, and select which courts you want to search.
