Core Data Performance

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.
