title: Mongo aggregation Match multiple values
body: <p>I have following documents</p>
  <pre><code>  {
         name: 'John',
         Address :'street 1 '
     },
     {
         name: 'Jane',
         Address :'street 2 '
     },
     {
         name: 'Smith',
         Address :'street 3 '
     }
  </code></pre>
  <p>I want to search the multiple document with different vales in mongo aggregation pipeline.</p>
  <p>That means <code>name =('John','Smith')</code>. I'm expecting result is</p>
  <pre><code>{
     name: 'John',
     Address :'street 1 '
  },
  {
     name: 'Smith',
     Address :'street 3 '
  }
  </code></pre>
  <p>My code is</p>
  <pre><code>db.articles.aggregate($match: { $or: [{ name: 'John' }, { name: 'Smith' }]);
  </code></pre>
  <p>This is giving an empty value.is it possible to get document like this way?</p>
