More on Solr vs ES faceting

I'm using 3.3 no NRT for the moment. We usually have two cores one Writing and one Reading and sending fake commits to Read core every 30-60 minutes.

I see. So when you said "Simple Searching during indexing ES is 50%
faster than Solr" was Solr really doing indexing and searching at the
same time?

It just seems that ES should be more than 50% faster than Solr 3.3
(without NRT) in a concurrent searching/indexing use case.
