使用Core Data时是否可以使用复杂索引？

I'm working on an iOS flash-card style learning app that, on load, needs to grab a bunch of data from Core Data. But the data I need is a fairly specific subset of the entity, based on user settings, so there are multiple predicates involved testing equivalence. I'm finding these fetches are super slow and, based on research on SQLite, I think an index would be a good choice here.I'm working on an iOS flash-card style learning
