What the heck does that mean? Do you want someone who doesn't have
the encryption key to be able to look up stuff in the collection? If
yes, the encryption doesn't sound so useful. If no, then what's the
problem? Just encrypt the whole file system that the database lives
on, and let users who have the encryption key access it in the normal
way.
