Yes, that is correct.
If you set the path.self property to true, the search will include the node specified in the path property as well as its children. If you set it to false, the search will only include the children of the node specified in the path property and will not include the node itself.
It's important to note that the path.self property is only applicable when performing a search using the path property. If you are not using the path property in your search, the path.self property will have no effect.
