QUESTION
I'm going to integrate my Neo4j application with Elasticsearch. I'm going to try the following Neo4j plugin from GraphAware https://github.com/graphaware/neo4j-to-elasticsearch
Could you please tell does it support Neo4j 3.1.3 version? Also, what version of ES should be used there ? Does it support ES 5.3.0 for example ?
Right now I have installed Elasticsearch 5.3.0 locally. Also I have added 2 jars:

Answered 2017-Apr-20 at 19:11It seems our documentation has been weird about the usage of the internal id as document id :
Replace this line :
com.graphaware.module.UIDM.uuidProperty=ID()
By this
com.graphaware.module.ES.keyProperty=ID()
However if you use the uuid module as well, it is best to use "uuid" instead of the internal ID
I tested on community 3.1.3 with the versions mentioned and it is working.
{
"took" : 1,
"timed_out" : false,
"_shards" : {
"total" : 5,
"successful" : 5,
"failed" : 0
},
"hits" :{
"_index" : "neo4j-index-node",
"_type" : "Decision",
"_id" : "2",
"_score" : 1.0,
"_source":{"id":123,"title":"Ibiza"}
}, {
"_index" : "neo4j-index-node",
"_type" : "Decision",
"_id" : "3",
"_score" : 1.0,
"_source":{"id":123,"title":"Weird Decision"}
} ]
}
}
If your nodes have both labels Decision and Votable, then you have to exclude them in the configuration like this :
com.graphaware.module.ES.node=hasLabel('Decision') && !hasLabel('Votable') && !hasLabel('BaseEntity')
