Sure,
The article I read said something like:
"Executing a fetch request requires a round trip to the persistent
store.... you can avoid the overhead of executing the fetch request
by searching the managed object context..."
Something like that, to be honest I can't find it any where in the
documentation and I only posted because I started to think I might
have been imagining things.
Hope this helps.

um, to execute a fetch request you do query the managed object
context. Can you clarify what you mean a little more?

I know that this subject has been covered many times and all the
related posts are very useful. However, I was reading the
documentation recently and I'm sure that I read somewhere that
there is a way to query the Managed Object Context instead of
executing a fetch request. But since then I have not been able to
find it in the documentation again. Was I just imagining things or
is there a way to do this? Will the performance difference be
vastly different?
Many thanks,
Phil.
