Dynamic Multi Search for EPiServer Find

EPiServer Find’s MultiSearch is great, but has a couple of limitations: All searches need to have a common return type, and IContent searches has to be projected to avoid deserialization errors. 
EPiCode.DynamicMultiSearch removes these limitations.

How it works:
Invoke DynamicMultiSearch and GetDynamicResult to retrieve the result sets

IEnumerable<SearchResults<dynamic>> result = client.DynamicMultiSearch()
    .Search<Product>(x => x.Filter(p => p.ProductTypeId.Match(5)))
    .Search<ArticlePage>(Language.English, x => x.For("lemon")) // works with IContent
    .Search<Book>(x => x.Filter(b => b.Title.AnyWordBeginsWith("lemon")).Skip(20).Take(20)) // individual skip and take per query
    .Search<Person>(x => x.For("Per Magne").Select(p => p.Name)) // works with projections
    .GetDynamicResult()

 

Use GetResultSet to retrieve the result set, which accepts an int. This number should match the order in which the search was added

var products = result.GetResultSet<Product>(0);
var articlePages = result.GetResultSet<ArticlePage>(1);
var books = result.GetResultSet<Book>(2);
var personNames = result.GetResultSet<string>(3);

Can we use statistics also with dynamic search without adverse effect to Search Without Hits Interface? :)
