title: How to properly use MATCH inside UNWIND for a Nebula query
body: <p>I’m currently working with the Nebula graph database for the first time and I’m running into some issues with a query. In terms of the schema, I have “Person” nodes, which have a “name” property, as well as Location nodes also with a name property. These node types can be connected by a relationship edge, called HAS_LIVED (to signify whether a person has lived in a certain location). Now for the query, I have a list of names (strings). The query looks like:</p>
  <pre><code>UNWIND [“Anna”, “Emma”, “Zach”] AS n
  MATCH (p:Person {name: n})-[:HAS_LIVED]-&gt;(loc)
  RETURN loc.Location.name
  </code></pre>
  <p>This should return a list of three places, i.e. [“London”, “Paris”, “Berlin”]. However, I am getting nothing as a result from the query. When I get rid of the UNWIND and write three separate MATCH queries with each name, it works individually. Not sure why.</p>
