Current filtering method for domain objects in the Data Index Graphql endpoint, allows a single String, exposing the underlying Infinispan query api. Although it is powerful, a more consistent approach would be to have a typed system similar to the filters that are done for ProcessInstances and UserTaskIstances.

• Ex current approach:

  Travels(query: "from org.acme.travels.travels.Travels t where t.traveller.firstName:'ma*'")
  

• Ex query using typed system:

  ProcessInstances(filter: {id: ["abb9f626-8a54-444d-943a-25b969a2cd1c", "446fcdb8-aa79-4044-baf9-6c471e0fbe1b"]})
