1、A Guide to ApplicationDevelopment2 = actors are created from Groups defined in the project file. The IDU cover contains the group ID in a field called ACTOR3 = actors are created based on a query string specified for the actorGroup in the project file4 = a single actor is created from a single Actor

Large values make take a long time to build the index. You should set this to whatever the maximum distance any of your spatial queries, Ex
