How to pass a text field value to a query string in asp.net mvc

Question

Another newbie with ASP.NET MVC! All I intend to do is search for a text field on my page, if I type and click on search, the URL to be redirected should have the following at the end, for example, in stackoverflow,

/search?q=searchedtext

So here is what I have,

<input id="searchText" maxlength="100" type="text" name="query" />
    <a href="???"  class="searchButton">        
        Search        
    </a>

I have a function in my controller, for example,

public ActionResult Search(string query)
 {

 }

Here is the route

routes.MapRoute(
            "Search",                                            
            "Search",                          
            new { controller = "Posts", action = "Search"} 
        );

Can anyone fill in the blanks here :). Any comments appreciated.
