title: Mongo Repository find by condition is not working
body: <p>I have a MongoRepository query method which needs to fetch data based on conditions.</p>
  
  <p>I have the following record in database.</p>
  
  <pre><code>{
  'name' : 'test',
  'show' : false,
  'free' : true
  }
  </code></pre>
  
  <p>And the following query, But the query doesn't return this record.</p>
  
  <pre><code>repositiry.findByNameNotNullAndShowIsTrueOrFreeIsTrue()
  </code></pre>
  
  <p>as per the condition, <code>Name</code> is <code>not null</code> and <code>Free</code> is <code>True</code>. But Why am I not getting the record.</p>
