Answer 1

SpecificFinder is meant to find "one specific instance" of the entity
Finder is meant to find "zero, one or more instances" for an entity

for example

Customer GetCustomer(int id);
Customer[] GetCustomers(string filter);

From the above methods, GetCustomer can become specific finder whereas GetCustomers can become finder.
