Index memory should fit in WiredTiger memory (50% of total memory)?

Hi,

I’ve learned that Wired Tiger uses/should be configured with ± 50% of all memory available to MongoDB.

I also have learned that, for best performance, all indexes should fit in the memory.

My question is if the indexes should fit in the Wired Tiger part of the memory (50%) or in all the memory available.

Thanks in advance.
