Exception in search functionality

Changed casting from Int to Double for country budget when country with 'max country budget' was searched, although I haven't found any use of the resultant country.
I __think__ it was a left over from the old way of suggesting a country.  Once upon a time in search when you wrote a country name and got back more than one country matching the query (e.g. Africa) the suggestion would be the country that had the biggest budget (hence the `val`).  Instead of a single country being passed in now we pass every country in but the `val` wasn't removed.
