I am just curious about how does the document count or document size per index impacts the search queries. I can shrink the size of each document on an index, but not sure if it will benefit the reading process or not.

I know the best way to answer my question is to benchmark the real dataset. Just wondering if anyone has the idea or already done the similar benchmarks.
