Hello, Some update: After fighting dependencies, especially logging libraries, I discovered that not only SolrJ is using Lucene but DSpace uses it directly in its search. And naturally Lucene has change a good deal between versions. End of that road. I am now rewriting our ElasticSearch interact

Hi Andrea, hi Helix, First of all thank you both for your replies. Your question is a very good one. I entirely agree. Unfortunately I am not aware of a ElasticSearch client library. Before integrating ElasticSearch in our DSpace I have not worked with ES before, meaning I followed the guides
