Module Builder Front-end control Filtering

I have a module that I created with the module builder.  I have a custom classification, products, that I need to use to limit the list.  I have found the field "AdditionalFilter" in the dynamiccontentmasterview settings.  I see that it takes some json when filtering by categories or tags.  I want to know how I can use this with my custom classification.  

This is what the field is set to when I use a category:

   "__msdisposeindex":180,
   "Title":null,
   "Id":"00000000-0000-0000-0000-000000000000",
   "QueryItems":[
     
         "IsGroup":true,
         "Ordinal":0,
         "Join":"AND",
         "ItemPath":"_0",
         "Value":null,
         "Condition":null,
         "Name":"Categories",
         "_itemPathSeparator":"_",
         "__msdisposeindex":267
      ,
     
         "IsGroup":false,
         "Ordinal":0,
         "Join":"OR",
         "ItemPath":"_0_0",
         "Value":"967a19b4-4579-4e22-b3fb-669be270fc37",
         "Condition":
            "FieldName":"Products",
            "FieldType":"System.Guid",
            "Operator":"Contains",
            "__msdisposeindex":268
         ,
         "Name":"twinkies",
         "_itemPathSeparator":"_",
         "__msdisposeindex":269
     
   ],
   "TypeProperties":[


   ],
   "_itemPathSeparator":"_"



I tried this and it excepted the query as valid, but it didn't filter:

   "__msdisposeindex":180,
   "Title":null,
   "Id":"00000000-0000-0000-0000-000000000000",
   "QueryItems":[
     
         "IsGroup":true,
         "Ordinal":0,
         "Join":"AND",
         "ItemPath":"_0",
         "Value":null,
         "Condition":null,
         "Name":"products",
         "_itemPathSeparator":"_",
         "__msdisposeindex":267
      ,
     
         "IsGroup":false,
         "Ordinal":0,
         "Join":"OR",
         "ItemPath":"_0_0",
         "Value":"BDDA2BD6-2139-4329-8308-B98AF9968B0B",
         "Condition":
            "FieldName":"products",
            "FieldType":"System.Guid",
            "Operator":"Contains",
            "__msdisposeindex":268
         ,
         "Name":"twinkies",
         "_itemPathSeparator":"_",
         "__msdisposeindex":269
     
   ],
   "TypeProperties":[


   ],
   "_itemPathSeparator":"_"


I basically just changed the names and GUID.  Any thoughts would be appreciated.

I wasn't ever able to get this to work.  I ended up moving the classifications to a standard category.
