This feature is disabled at the moment, because in some cases the "Search Request Done" packet will be handled before the last "Search Request Entry":
- Mulitple internal goroutines to handle network traffic
Makes library goroutine safe
Can perform multiple search requests at the same time and return
the results to the proper goroutine. All requests are blocking requests,
so the goroutine does not need special handling
