Hello,

I'm trying to run facets against big index (45M docs) and have some  
questions:

1. Since the number of terms is unknown, I tried passing  
Integer.MAX\_VALUE as a size  
( addFacet( FacetBuilders.termsFacet( "facet1" ).field( "runId" ).size( size ).global( true ) )

- this caused exception in server, is this expected?

org.elasticsearch.transport.RemoteTransportException: [Catiana][inet[/  
10.80.0.23:9300]][search/phase/query]

1. Following the above, how one should do facets queries against big  
index, I used to paginate queries with setFrom(), but it's not  
available for facets.

3.Is the data known ahead to ES (during the index build) or it re-  
calculated every call?

Thanks!
