I'm having trouble using Skip() and Take() to acheive pagination on a set of Examine SearchResults, getting an error

macroScripts\SearchResults.cshtml(46): error CS1973: 'System.Linq.IQueryable' has no applicable method named 'Skip' but appears to have an extension method by that name. Extension methods cannot be dynamically dispatched. Consider casting the dynamic arguments or calling the extension method without the extension method syntax.

Abbrieviated source;

var pagesToList = ExamineManager.Instance.SearchProviderCollection["ContentSearcher"].Search(filter).Distinct().AsQueryable();

// lots of pagination stuff trimmed

@foreach (var item in pagesToList.Skip(currentPage * itemsPerPage).Take(itemsPerPage))   
{
    <li>@item.Name</li>
}

Surely Skip() and Take() should be available? I've tried casting pagesToList to a DynamicNodeList, and no luck there either?
