Wildcards
You may need to find variant forms of the words you are searching for. Some programs have a "wildcard" function. This allows you to type in a symbol to indicate variant words. Some examples are the asterisk (*), dollar sign ($), or question mark (?). They are used at the end of words to find plural or related forms and within words to find alternative spellings.
Child? may find: Children, childhood, childlike, etc.
Behavio?r may find: Behavior, behaviour, etc.
Book* may find: Book, books, etc.

Boolean Operators

AND

'chocolate AND ice cream'

This means you are combining two concepts. The search will find materials with both words. A search for "chocolate AND ice cream" provides information relating to chocolate ice cream. AND is used to narrow your search; you can use AND to add other words to form a more specific search.
That's a lot of chocolate ice cream.

OR

'chocolate OR ice cream'

This means you are searching for documents containing either of the words. So a search for "chocolate OR ice cream" would provide information related to all kinds of chocolate and information related to all types of ice cream. OR is used to broaden a search and is helpful to link two synonyms together.
chocolate
ice cream

NOT

'chocolate NOT ice cream'

This operator means you are searching for specific information. A search for "chocolate NOT ice cream" would provide all documents about chocolate not including documents about chocolate ice cream. NOT is used to narrow a search and remove words that are not relevant to your topic.
