Clarify description of prefetchMaxSearchSize. (#4338)

Browse source 
This is a comments only change that fixes two problems:

1. The previous comment described it as limiting request size, but it
   instead limits the response size.
2. Previously it was unclear _why_ this size was significant. It wasn't
   obvious to me that the entire response would be stored in memory.
