as long as only one process is writing to the index that’s fine. But you

How does that work in a normal Rails application if you run in a
production environment (ie cluster of Mongrels, FCGI or SCGI where you
always have a number of processes running)? I mean, every instance of
the Rails env might want to add something to or read from the index.
there’s a file based locking mechanism, Ferret’s index class handles
possible collisions by waiting and retrying the write after a short
It also handles re-opening the searcher for you.
If you don’t use the Index class it’s up to you to detect changes to the
index and re-open your searcher. there’s a method named latest?
somewhere, you could look into the Index class to see how it’s done
