createNodePropertyIndex
```
public final void createNodePropertyIndex(java.lang.String propertyName)
```
Create an index for specified node property. Whenever an element has the specified key mutated, the index is updated. When the index is created, all existing elements are indexed to ensure that they are captured by the index.

public boolean isIndexed(java.lang.String propertyName)

public void putIfIndexed(java.lang.String key,
                         java.lang.Object newValue,
                         NodeRef nodeRef)

public final void dropNodePropertyIndex(java.lang.String key)

Drop the index for specified node property.

getIndexedNodeProperties
```
public final java.util.Set<java.lang.String> getIndexedNodeProperties()
```
Return all the keys currently being indexed for nodes.

public final int getIndexedNodeCount(java.lang.String propertyName)
