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 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 (*).
