Mac OS X 10.4 features Spotlight, which you can use to quickly find information on your computer. Spotlight can find files as well as information in files. For example, if you want to find files on your computer that contain the words—HDTV, project, bid, and budget—Spotlight can quickly list all email messages, documents, and other files that are named with or contain those terms.
When you do a search using Spotlight, you're actually accessing a comprehensive, constantly updated index that sees all the metadata inside files—not only the "what, when, and who" information, but the content kind, author, edit history, format, size, and many other details.
However, there are some places that Spotlight won't search, such as certain "invisible" areas in the Mac OS X file system, and in user areas that do not belong to you (if your computer has multiple users). You can also set Spotlight to not search in certain areas for privacy—open System Preferences, click Spotlight, then click the Privacy tab to select your off-limits areas.
In the case of Final Cut Pro, Spotlight won't search its built-in Help PDF files because they're contained within the Final Cut Pro application itself. To get these documents into Spotlight's search scope, save the files outside of the application. Spotlight will then be able to index the documents. Afterwards, when you do a search and select one of these documents in the search results, Spotlight will open the PDF in Preview and highlight every instance of the search string you entered.
Here's how to save the Final Cut Pro Help files outside of the application for Spotlight searching (we're using Final Cut Pro 5 as an example, but the same general methods apply for Final Cut Pro 4 and Final Cut Pro 4.5 HD).
