title: Neo4j: Step by Step to create an automatic index
body: <p>I am creating a new Neo4j database. I have a type of node called User and I would like an index on the properties of user <strong>Identifier</strong> and <strong>EmailAddress</strong>. How does one go setting up an index when the database is new? I have noticed in the neo4j.properties file there looks to be support for creating indexes. However when I set these as so</p>
  
  <pre><code># Autoindexing
  
  # Enable auto-indexing for nodes, default is false
  node_auto_indexing=true
  
  # The node property keys to be auto-indexed, if enabled
  node_keys_indexable=EmailAddress,Identifier
  </code></pre>
  
  <p>And add a node and do a query to find an Identifier that I know exists</p>
  
  <pre><code>START n=node:Identifier(Identifier = "USER0")
  RETURN n;
  </code></pre>
  
  <p>then I get an</p>
  
  <pre><code>MissingIndexException: Index `Identifier` does not exist
  </code></pre>
  
  <p>How do I create an index and use it in a start query? I only want to use config files and cypher to achieve this. i.e. at the present time I am only playing in the Power Tool Console.</p>
