janusgraph-berkeleyje-se-server.properties

# place in conf/gremlin-server/
gremlin.graph=org.janusgraph.core.JanusGraphFactory
storage.backend=berkeleyje
storage.directory=db/berkeley
index.search.backend=elasticsearch
index.search.directory=../db/es
index.search.elasticsearch.client-only=false
index.search.elasticsearch.local-mode=true

I presume janusgraph-berkeleyje-se-server.properties should be janusgraph-berkeleyje-es-server.properties
es for ElasticSearch

Probably? it was three years ago and I haven't touched this stuff since. :)
