 This is a tutorial on Boolean Searching from Bellevue College Library. In this video, you will learn to become a power searcher. Library databases have scholarly articles and the information you need for your assignment, but they don't work the same as a search engine like Google. So you can use the techniques in this video to become a power searcher. Let's upgrade our search skills with Boolean operators. So, what are they? Boolean operators are short, connecting words typed in all caps that help you optimize your database search, and narrows your search, or broadens your search, and not excludes specific search terms. Let's try a search. Search with and to tell the database that all search terms must be present. Here I am using the ProQuest database to search for crows and communication, and I get a lot of results. Search with or to tell the database that any of your search terms can be present. I add the or operator to search for crows, or ravens, and communication, and I get even more results. Search with not to tell the database to ignore concepts that may be implied by your search terms. It looks like a lot of the results in my previous search were about communication and the football team, the Baltimore ravens. So I'm using the not operator to exclude Baltimore or football from my search results, and you can see I get quite a few fewer than before. And that's it. Have questions? Ask a librarian for help.
