Notes about searching in WorldCat Discovery:
- By default, searching from the search box in WorldCat Discovery will automatically apply the keyword index
- Searches that contain index labels and Boolean operators can be entered in any search box in WorldCat Discovery
- When searching on the Advanced Search screen, if you use an index in a search field, you must use indexes for all search terms
- An AND boolean operator is inferred when using search terms without quotes or parenthesis
An index is two characters followed by a colon (:) or by an equal sign (=).
- Use a colon to search for the words anywhere in the specified index. For example: rs:unrestricted
- Use an equal sign to perform a phrase search. For example: rs=unrestricted online access

Enter the first three characters of the term (at a minimum) and follow with an asterisk (*).
Example of terms in search results: securit-y, securit-ies, or securit-ization
Example of search: securit*
Enter the first three characters of the term (at a minimum) and follow with a wildcard. WorldCat Discovery supports the use of two wildcard characters the pound sign (#) and the question mark (?).
Use the pound sign to represent a single character.
Use the question mark to match missing (zero) and up to nine characters including no additional characters.
