I'm working on a app in Node/Express/Jade environment. 

Let's assume I start my app, and direct my browser to this URL:

```
/superadmin/?year=2012

```

On this page, i find a list with object, sorted in a default order. Here is also a link that will re-sort the list objects in another order. I jade this link look like:

```
a(href = '?sortAfter=company&ascending=1') Company

```

If i press this link, I *will* get the items sorted in the way I want, but the ?year=2012 from earlier query string will be lost. 

**Question:** How do I re-write this link to *add* the new query strings, and not *replace* it.
