I have done these types of searches. I could not figure out how to set up the security stuff of entering passwords. You could try the following which should not be too hard to code. I figure everyone has the right to look at what they own so limit the searches by starting them at the user's home file (/Users/"ownerName"). You could test the file name for this "prefix" & proceed if the test passes. You can use the NSString method "hasPrefix:" to do the test. You can probably find the home directory, though I have not tried this lately, by using Foundation functions. Try NSHomeDirectoryForUser(NSUserName()) & see if this helps. Of course, it won't help if you are looking at a flash drive!
