No single search site can keep up with all of the content on the Internet. That is one reason why you can get very different results from different search sites.
Another is how search sites get the web pages they list. Some have robots or spiders (computer programs) that search other sites on the Internet, some have pages based on data input from people and others have a combination.

You can then scan their bibliographies for more papers on your topic.
Use synonyms of your search term (e.g. Native Americans, American Indians, indigenous peoples, etc.)
