问题
Can I use the Spotlight APIs (they exist, right?) in Cocoa to determine if Spotlight (in the upper-right corner) would match a given filePath with a given string?
In other words, given a filePath such as "/Users/enchilada/Desktop/MapOfUSA.pdf", and a string such as "Virginia", how would I tell if Spotlight would show this file when "Virginia" would have been typed in the upper-right Spotlight search? (As you can imagine, in the example shown, it would probably be matched, because a PDF map of the USA probably contains Virgina.)
If possible, a simple code piece to do this would be appreciated.

You can use the NSMetadataQuery class or its underlying CFType MDQuery. O'Reilly has published an example.
