These strategies will help you search, whether you are using library databases, online resources, or books.
Boolean operators such as AND (narrows) and OR (broadens) are used to join search terms together.
Use OR to broaden your search. For example, if you search advertising OR commercials, you will find articles that include both terms.
In contrast, use AND and NOT to narrow your search. For example, if you search advertising AND commercials, you will only find articles that include both terms.
And, if you search advertising NOT commercials, you will find articles that include the word advertising except for those that also include the term commercials. In Google, use a minus sign instead of NOT (e.g. advertising -commercials).
Quotation Marks are used to search for a specific phrase. They limit or narrow your search.
Truncation allows a search engine to look for variant endings of a word. Use a symbol (* is the most common) at the end of a truncated word. Truncation broadens or expands your search.
Some databases also allow you to use a symbol at the beginning or in the middle of a word
You can use multiple search strategies simultaneously.
