Hi,

Let's say we have facets that are quite dynamic that an editor can create by editing a field in EPiServer which makes it hard for us in the code.

I've made a model that holds all TermsFacets with TermCounts and which ones that are selected (by parsing the querystring) and each TermCount's url. Basically everything you need to render everything.

This makes it easy to bind the data to two nested repeaters, one for the TermFacets and the other one for the TermCounts. This makes it also easy to make it possible to select TermCounts from two different TermFacets, because all selected TermCounts is stored in the same querystring parameter prefixed with the name of the TermFacet.

The TermsFacets and TermCounts was easy to get hold off and parse. But when one TermCount (with its corresponding TermFacet) is selected how can I  add that term to the Filter with just a string representing the TermFacet and one one with the value?

I have a NameValuCollection (the Filter property in the code example below) where the key is the TermFacet and the values is the selected TermCounts.

foreach (var value in Filters.GetValues("SearchTypeName"))
{
    filter = filter.And(x => x.SearchTypeName().MatchCaseInsensitive(value));
}

In this case I have to know which property/method (SearchTypeName()) I want to filter by. Is it possible to do something like this!?

foreach (var key in Filters.AllKeys)
{
    filter = filter.And(CreateFilter(key).MatchCaseInsensitive(Filters[key]));
}

Hope all this makes sense...
