A major problem with searching Google or any other web search engine is that you usually get a huge number of results for almost any search Let's say I'm working on a paper on medical research performed on animals and I do a Google search We'll see right up here that I have gotten about 10,700,000 results If you only need one or two good websites for your paper this is absolutely a waste of your time. You can help this problem some by making use of Google's advanced search, which you can access by this link right over here under the search tab. When we come here, first of all it's important to understand how Google searches. Up here are the words I typed. It's taken them in the advanced search screen and put them next to a box that says all these words. No matter how many words you put into a Googlel search box it searches for each of those words individually on any given web page. That's one of the reasons you get back so many results. Now sometimes you have words that you want to have appear as a particular phrase-- in this case "medical research". We want those words to appear together. So I can take them out of this search box and instead put them into the search box below that says this 'exact wording or phrase.' When I do that notice that in the top search box here it has put them in quotation marks. You can actually do that on the main Google screen. Sometimes I will use the box below as well that says 'use one or more of these words.' Notice that there are three boxes divided by the word OR. You can use that if there are synonyms or related terms you want to search for. So let's say I am particularly interested in monkeys or chimps. Sometimes, the box below is also very useful. It says don't look for any pages that have in any of these unwanted terms. So, if I was still getting back a lot of sites that dealt with lab rats, I could put 'rats' in here to try to get rid of those sites. The other box I use very frequently is the last one that appears on the advanced search page. This one allows you to limit your search to a specific domain. I often use this to limit my searches to the .org domain, .gov domain, or .edu domain, where I think I'm more likely to find good sources. Now if I hit search, We can see I've brought my results down from more than 10,000,000 to 81,400 results. Keep in mind that you need to evaluate any web site before you use information from it in a research paper. That will be the topic of the next video.
