/*
* THESE METHODS ARE A TOTAL HACK
* They exist to work around a bug in Sitecore (7.x-8.0 at least) where it uses private reflection
* in such a way that it breaks all derived classes of LinqToLuceneIndex when GetResults() is called
* on the queryable (#4 on GitHub)
*
* These basically act as proxies so the private reflection in Sitecore hits these methods,
* which then reflect the call down to the base class' private method as is expected.
*
* Source of hack: the Execute() method on the base class doing this:
* MethodInfo methodInfo1 = this.GetType().GetMethod("ApplySearchMethods", BindingFlags.Instance | BindingFlags.NonPublic).MakeGenericMethod(type);
* MethodInfo methodInfo2 = this.GetType().GetMethod("ApplyScalarMethods", BindingFlags.Instance | BindingFlags.NonPublic).MakeGenericMethod(typeof (TResult), type);
*
* The this.GetType() cause it to look for the private methods on any derived classes, where they do not exist.
