You are able to search for variations of a word to help expand your search. Truncation, represented by an asterisk (*), allows you to replace one or more letters of a word to find other forms of that root word.
For example, type teen* to find the words teens, teenager, or teenagers.
You can also use quotation marks ( " ") in your searching. Quotation marks tell a database you want your terms to come together in the results.
The most common type of search is a subject search; you are looking for information on a subject. However, you can also do keyword and text word searches. Each type of search will give you a different number and list of results.
AND, OR, and NOT are used to combine words together. Each word tells the computer how to search each term in relation to the other term(s), and will give you different results.
