Using AND, OR Searching
Connecting keywords with the words AND or an OR will define how the keywords work together.
If you connect keywords with an AND you are telling the database: "the following keywords must be in every article in my results!" For example, Literature AND Criticism. Every article or book in your search must have the keyword Literature and the keyword Criticism. If it does not have both keywords, it will not be included in the results. You can search more than two keywords at a time, for example Literature AND Criticism AND Shakespeare. Now all three keywords MUST be in every article or book.
