Yes, I am using an sqlite store, but I tried it with the other store types and it did not work either. What would a working predicate look like for other store types?


I didn't catch this at first, but you said you're fetching employees where "employee.salary ...". If the target entity for your fetch is Employee, does Employee really have an attribute named "employee"? Are you sure you don't mean where "salary ..."?


Sadly, in-memory filtering is not an option for it has to happen in a single fetch.

That you said this without explaining why leads me to suspect this isn't the case. Even if you have a hundred thousand employees, I can't see how in-memory filtering is "not an option". Please explain.
