You almost certainly shouldn't do that. You should simply execute
one fetch request to retrieve all the data you want, and then
filter appropriately in memory.
I had reached the conclusion after reading the docs that this is
what I would have to do. I just wanted to check to see if I was
missing something.
When you say that I shouldn't do it the way I wanted to, what
reasons do you have? Because the API does not effectively support
it, or something else?
