How to exclude multiple property keys from the Elasticsearch index when using GraphAware neo4j-to-elasticsearch integration

Question

In the GraphAware neo4j-to-elasticsearch library I can see this property setting as a route to excluding certain Neo4j node properties from the Elasticsearch index:

com.graphaware.module.ES.node.property=key != 'age'

which works perfectly for a single property. But I can't see any documentation for how to specify multiple properties. I've made trial and error attempts with additional property names: comma separated; space separated and lots of other more left-field options but haven't had anything work yet.

Anyone have any experience in this area?

I'm using Neo4j 2.3.2 Enterprise and the appropriate GraphAware library versions.

Answer 1

The setting syntax comes from the Inclusion Policies :

https://github.com/graphaware/neo4j-framework/tree/master/common#inclusion-policies

For excluding age and name you can do :

com.graphaware.module.ES.node.property=key != 'age' && key != 'name'

I will amend to readme to provide a link to the Inclusion policies documentation.
