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, FUTURE AND RACIAL DIVIDE. Every article or book in your search must have the keyword FUTURE and the keyword phrase RACIAL DIVIDE. 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 FUTURE AND RACIAL DIVIDE AND UNITED STATES. Now all three keywords MUST be in every article or book.
OR allows a researcher to use synonyms and related terms to expand a subject (Ex. woman or female) (use or abuse) etc.
