2.2 Search engines

Many of you use Google every day. You may trust that it will quickly and easily find exactly what you want. While Google is certainly the largest and most heavily used search engine, there are plenty of others available. Examples of other search engines include Bing, DuckDuckGo, and Yahoo. Each search engine uses different ranking systems, which affect the number and order of your search results. This discrepancy can make it difficult to replicate search results or to share a search with a friend. Even if you use the same search engine and keywords, the search history on the computer you use also affects the list of results you retrieve. For example, someone in Kentucky would likely have a different search history than someone from another state. They may have searched for topics like UK basketball, the Kentucky Derby, Mammoth Cave National Park, or the best bourbon manufacturers. These search patterns reflect regional interests and activities, which can influence the content and advertisements shown to them online. Try experimenting with different search engines to find the one you prefer.

How Search Engines works

Search engines are run with proprietary algorithms and ranking systems to interpret search terms and give the user access to results that the search engine decides is relevant. For everyday, quick searches, this can be helpful. However, the top results may not be the best sites for your intended purpose. While the specifics of each search engine’s algorithm are not publicly known, the companies do share some basic functions and restrictions of each. For example, Google is clear about how it tracks user data and uses it to personalize its ads. On the other hand, the search engine DuckDuckGo prioritizes user privacy and does not track user data.

Every search has a different context. Sometimes you just need basic facts and news and, in that case, Google would be a good option. However, if you need scholarly information, Google may not be your best choice. If you rely on typical web search engines for all your information needs, you will miss some of the scholarly information on your topic some scholarly sources will be behind a paywall.

Let’s say you need to write a paper about Jane Goodall, a world-renowned researcher and activist who has studied chimpanzees since the 1950s and published her research in more than 100 scholarly articles. When you Google Jane Goodall, you’ll find websites related to her organizations, a Wikipedia entry, her Twitter feed, photos and videos, links to buy her books, and news articles. All of this may be good information, but most of it is not peer-reviewed scholarly material. If your professor requires you to use only peer-reviewed sources in your work, it will be necessary to go beyond Google to find what you need.

Google Scholar

Google Scholar is similar to Google except that it typically excludes non-scholarly web content because its primary purpose is to find scholarly materials. These include journal articles, books, patents, legal documents, reports, and more. However, there’s no easy way to separate journal articles from other resources covered by Google Scholar, including some digitized books and scholarly websites. You may also find things you wouldn’t expect like course syllabi and PowerPoint slides.

One of the most important things to understand about Google Scholar is where its content comes from because that determines if and how you can access it. Much of the material you find there comes directly from the open web. For example, it’s common to see pdf files from researchers’ websites, open access articles, and similar links in your Google Scholar search results. These types of materials are available to anyone, anywhere. You shouldn’t have to log in to any website or database to access these materials.

Mixed in with these open web materials, you’ll also find paywalled materials, including subscription journal articles and e-books. In most cases you can still access these, though it may take a few steps. Google Scholar has a feature that provides members of the NKU community with links to materials covered by NKU subscriptions. At home, make sure to connect to Google Scholar via the library website for more access.
