title: How to search all nodes within particular radius using latitude and longitude in neo4j
body: <p>I have two types of nodes Idea and Location, Idea contains some general information and Location node have 3 properties its id, latitude and longitude. The relationships between these nodes is of following types:</p>
  
  <pre><code>    (i:Idea)-[:DEVELOPED_AT]-&gt;(l:Location)
      (i: Idea)-[:DEPLOYED_AT]-&gt;(l:Location)
  </code></pre>
  
  <p>Now when a user search for any idea by geography using google place autocomple then I receive lat, long of searched location. Now I have to  return all the related ideas either developed or deployed within a particular radius of that searched location. On searching I came accross spatial Neo4j but I don't know how to use it. </p>
