title: I get colon with my param using express for node.js
body: <p>Here’s my routing :</p>
  
  <pre><code>router.route('/search:word').get(function(req, res) {
    var re = new RegExp(req.params.word, 'i');
    console.log(req.params.word);
  
    Place.find().or([{ 'title': { $regex: re }}, { 'category': { $regex: re }}]).sort('title').exec(function(err, places) {
      res.json(JSON.stringify(places));
    });
  });
  </code></pre>
  
  <p>When I use the request <code>/places/search:test</code> the console displays :test instead of just "test".
  Any idea what’s happening?</p>
