Hi Andy, Have you got it working use a text based query, that is, using the "query_string" member in JSON,direct to the ES API? --- No it is still not working. I am configuring ElasticSearch in Jena using a config ttl file. For using ES API can I do it from Jena UI using SPARQL or do I need to write any code for it? How to use the "query_string" member in JSON is it possible to append this in SPARQL?
