I have configured a  'nodeType' index for my modeshape repository, hoping to speed up my "SELECT * FROM [<type>]" queries. However, the index seems not to be used: It doesn't show up in the Query Plan and performance is the same with or without indexing, regardless of the <type> I am querying. I tried all three available index providers and the results are the same. Setting the logging level for org.modeshape.jcr.index reveals: "Considering index 'nodeTypes' in 'indexer' provider for query in workspace 'default". Looking at the HTTP traffic between modeshape and elasticsearch, I see absolutely no requests to ES when executing the query. My current repository configuration looks like this:

{
    "name": "My Repository",
    "jndiName": "jcr/My Repository",
    "storage": {
        "persistence": {
            "type": "file",
            "path": "${my.data.dir}/repository"
        },
        "binaryStorage": {
            "minimumBinarySizeInBytes": 4096,
            "minimumStringSize": 8192,
            "type": "file",
            "directory": "${my.data.dir}/repository"
        }
    },
    "indexProviders": {
        "indexer": {
            "classname": "local",
            "directory": "${converter.data.dir}/repository/indexes"
        }
    },
    "indexes": {
        "nodeTypes": {
            "kind": "nodeType",
            "provider": "indexer",
            "nodeType": "nt:base",
            "columns": "jcr:nodeType(STRING)"
        }
    }
}

I tested this with Modeshape 5.2 and 5.3. Is this the expected bevahiour? Am I missing something?
