Hi,

I am trying to get some search functionality working on a website and i was wondering why i am getting the below issue when following the documentation here:

My code:

@inherits Umbraco.Web.Mvc.UmbracoTemplatePage
@using Examine.LuceneEngine.SearchCriteria;
@{
    var query = "campaigns";
    var searcher = Examine.ExamineManager.Instance.SearchProviderCollection["ExternalSearcher"];

    var searchCriteria = searcher.CreateSearchCriteria(Examine.SearchCriteria.BooleanOperation.Or);
    var searchQuery = searchCriteria.Field("nodeName", query.Boost(5)).Or().Field("nodeName", query.Fuzzy()).And().OrderByDescending("createDate");
    var searchResults = searcher.Search(searchQuery.Compile());
    if (searchResults.Any())
    {
        <ul>
            @foreach (var result in searchResults)
            {
                <li>
                    <a href="@result.Url">@result.Name</a>
                </li>
            }
        </ul>
    }
}

Thank you :)
