title: Concat multiple query param in react-router
body: <p>I am using <code>react-router-dom</code> v 5.2.0. I want to add multiple query params in the URL and I'm not sure how to accomplish it.
  My route looks like this:</p>
  
  <pre class="lang-js prettyprint-override"><code>&lt;Route path="/admin/users" component={UserList} /&gt;
  </code></pre>
  
  <p>I want to pass multiple query params like...</p>
  
  <pre><code>/admin/users?search=hello&amp;page=1&amp;user_role=admin
  </code></pre>
  
  <p>Currently I'm doing it manually like...</p>
  
  <pre class="lang-js prettyprint-override"><code>&lt;Link to="/admin/users?user_role=admin" /&gt;
  </code></pre>
  
  <p>However, with this manual thing I cannot concat multiple query params. Is there a way to concat the query params dynamically? Does <code>react-router-dom</code> has it's own way of doing such things?</p>
