react-router match query string
<p><a href="https://github.com/reactjs/react-router/example" rel="nofollow">https://github.com/reactjs/react-router/example</a></p>

<p>I tried the example on <code>npm start</code></p>

<p>query string match to route is not working on the example.
When I click the second one, It's activating wrong one </p>

<p><a href="http://localhost:8080/query-params/user/bob?showAge=1" rel="nofollow">http://localhost:8080/query-params/user/bob?showAge=1</a>
and refreshing on the link above not matching any routes.</p>

<p>Even if I have change the example code to below
<code>
      &lt;Route path="user/:userID(?:showAge)" component={User} /&gt;
</code>
I tried couple of things that might work based on docs but none of them worked.</p>

<p>Am I missing something?</p>
