iOS 9 - "domainIdentifier" for CSSearchableItem

in the init for a CSSearchableItem, one of the parameters is a "domainIdentifier" which Apple writes in its docs is the item's "associated ID." What is this?

The Domain identifier is the group name to be indexed. For example if you index all contacts from app use can use like as follows:

searchableItems=[[CSSearchableItem alloc]initWithUniqueIdentifier:identifier domainIdentifier:@"contacts" attributeSet:attributeSet];

The domain identifier name is used to easily delete all index in that domain like this :

[[CSSearchableIndex defaultSearchableIndex]deleteSearchableItemsWithDomainIdentifiers:@[@"contacts"] completionHandler:^(NSError * __nullable error) {

        if (error!=nil)
        {
            NSLog(@"%@",error.description);
        }
        else
        {
            // Indexes deleted successfully
        }
    }];

domainIdentifier is a way to group several searchable items together. You will use it to restore/update/delete groups of items, when needed.
