You cant do that with GetFinds
There are two alternatives, one is to include a list with all other types in the filter. the other is to filter in the code.
The problem with the first meted is if new types are added and longer/more complex challenges configs. And the problem with the second one is a bit more complex code.
It is probibly best to include a exclude filter in code and include the types filter in the checker to make it easier for challenges taggers.
If I am not mistake the filter code is 6 lines
for i,v in IPaires(conf.excludedTypes) do
And in the loop of myfinds result
if excludedTypes[v]~= nil then
A what i hope is a complete list of cachetypes is i JSON
