Searches are not case-sensitive. For example: "photoshop", "Photoshop", and "PhotoShop" are identical. Multiple keywords should be separated by a comma. For example: enter "xxxx, yyyy" to search for the words "xxxx" AND/OR "yyyy". You can select which Boolean value ("AND" or "OR") to use with your search. "AND" searches return results containing all of your keywords. "OR" searches return results containing any of your keywords. "AND" searches are useful for specific topics, while "OR" searches are more general and return more results. [Tip: Also, make use of Netscape's or Internet Explorer's "Find..." feature in the "Edit" menu.] Boolean search using: and  or Maximum records returned: 25  50
