Spotlight importer for records

I'd like to make Spotlight index individual records from my 
application, rather than whole files.  Some examples of this are 
Apple's own iCal, Address Book, and Mail.app.  For instance if you 
type in someone's name in the Spotlight search box, in addition to 
files which contain that name, individual Address Book entries that 
match will show up, and selecting one of them will start Address Book 
with that address showing.  I'd like to implement the same sort of 
thing for my app, but the Spotlight Importer Programming Guide just 
shows how to generate metadata for files, but not how to get Spotlight 
to treat individual records as separate files.  Can someone please 
point me in the right direction?

Thank you,
Adam
