title: Cloud Datastore 'like' query
body: <p>I've an entity in Google Cloud Datastore. One of the properties is array of strings. For example: </p>
  
  <p><strong>property</strong>: skills</p>
  
  <p><strong>Entity 1:</strong><br>
  value: <code>["mysql","sqlserver","postgresql","sqllite","sql-server-2008","sql"]</code></p>
  
  <p><strong>Entity 2:</strong><br>
  value: <code>["css","css3"]</code></p>
  
  <p>Now, I need to query for those entities that contain array elements <code>css*</code> </p>
  
  <p>In typical SQL, it'll be <code>select * from kindName where skills like 'css%'</code></p>
  
  <p>I tried <code>select * from kindName where skills = 'css'</code>, which works fine but how can I get entities that have <code>css*</code> elements similar to the SQL query?</p>
  
  <p>Or</p>
  
  <p>What's the best way to model the data for this?</p>
