Hi,

I am trying to implement the umbraco Examine search as described in the umbraco website.

http://umbraco.com/follow-us/blog-archive/2011/9/16/examining-examine.aspx

But when I do a search on the page it gives an error message.

Error loading Razor Script JobSearch.cshtml
Object reference not set to an instance of an object.

Below are my configs and codes.

Any help would be much appreciated. :)
