You wouldn't want to store access rights info in the index, because access
rights change, and you also wouldn't want to depend on the current access
privileges scheme. The idea of trying to access the file is a good one.
You could also have an option to store the index on a per-folder basis.
This would slow down searches, but guarantee complete security.
