Subject Re: Using multiple CPUs for a single document base?

You say it like it's something you have control over; how would one 
choose to use more than one thread when indexing? I guess maybe it 
depends on how you're indexing of course; I guess if you're using SolrJ 
it's straightforward. What if you're using the ordinary HTTP Post 
interface, or DIH?
