Are there any simple ways of populating av ES IndexRequestBuilder from  
a populated Lucene Document instance, i.e. reading out all fields  
added to the Document instance and adding them to the  
IndexRequestBuilder (or a ES Request instance)

The concrete use case is:  
I have a JMS queue containing Lucene Document instance - and want to  
consume that queue and add the received Documents to ES - imlemented  
using a Es River, much like the way the elasticsearch-river-rabbitmq  
plugin does it, except that queue contains Lucene Document instances,  
not json-formated index requests.

The queue is fed by the Hibernate Search slave backend.

Any ideas?

Just go over the fields and build a json request with them. Should be  
simple now? No need to have a river for that.
