title: which nodejs index method is better
body: <p>According to the neo4j documentation, indexing can be done i 2 ways"</p>
  
  <blockquote>
    <p>Indexing in Neo4j can be done in two different ways:
    1. The database itself is a natural index consisting of its relationships of different types between nodes. For example a tree
    structure can be layered on top of the data and used for index lookups
    performed by a traverser.
    2. Separate index engines can be used, with Apache Lucene  being the default
    backend included with Neo4j.</p>

  <p>But there is no comparison which is better in what and what is better in which cases. </p>
  
  <p>Which one is better and why?</p>
