You can search the Master Index using a keyword search. When you click on an entry in the search results, the target book opens in its own window. In most cases, the book opens to the place in the text that is indicated by the entry.
To open the keyword search page, click on the sub-entry under Master Index in the General User Documents category list, as shown here, or click the Search by Keyword button in the Master Index book's button panel. Here, the user searches for the string "print," receives a list of matching entries, and chooses to view information about Advanced Printing Services in the System Administration manual.
