I dont know if is posible i have a few private forums that i dont want to be indexed by ES. Is a waste of time and space in disk. If possible exlcude certain forums to be indexed ??
If i remember well in vB every forum have this option.
It would more be a request for the core XenForo software since the ES addon really is just indexing what the core software wants to index. But that being said, how come you would never want to be able to search private forums (obviously only people with access would be able to)?
