Limitations about Indexed Items for CoreSpotlight?

I know that I can index a maximum of 32767 CSSearchableItem in my application.

Won't there be performance issues in a scenario where each application has the maximum number of indexes? How does the system deal with this situation?

Also, let's say an application indexes the most used 32767 words, won't it abuse the system in this way and be at the top of the search results? What does Apple do about this?

Is there documentation somewhere that specifically details this questions?
