title: Query with like in MongoDB
body: <p>How can I do a like query in MongoDB using Node.js?</p>
  
  <p>Here's my source code, but it doesn't work:</p>
  
  <pre><code>exports.findAll = function(req, res) {
      var country=req.params.country; 
      db.collection('wines', function(err, collection) {
          collection.find({ 'country': new RegExp('/'+country+'/i') }).toArray(function(err, items) {
              res.jsonp(items);
          });
      });
  };
  </code></pre>
