Core Data search optimization


  • Subject: Core Data search optimization

Hello,

I can't seem to find any discussion about this, but I have this
question after I watched session 137 of WWDC about core data
optimization.

So, Melissa Turner advise to use <= and < instead of BEGINSWITH, but
how do I do that with predicate substitution variables or formatted
predicate?

Let's use this example:
@"franc" <= searchName AND searchName < @"frand"

What if @"franc" is the search keyword variable that is obtained from
the search bar text input?
How do I increment the suffix or the overall NSString variable?
