Hi

I need to band a set of results so that there are a number of custom bandings (represented by a numeric search priority) then ordered by relevance within that band. So far I have got 

ITypeSearch<ProductPageBase> result = resultsBase.OrderBy(x => x.SearchPriorityEffective);

to do this. Unfortunately this bands the results but destroys the relevance ordering within that banding. What would be ideal is if I could go

ITypeSearch<ProductPageBase> result = resultsBase.OrderBy(x => x.SearchPriorityEffective).ThenBy(x => x.Relevance);

but i can't see anywhere that the relevance of the search result is directly exposed. Does anyone know of a way to achieve this kind of sirting in find i.e. CustomSort -> then by -> relevance of the search results

Many Thanks for any all help
