what means

FastSearchSkippingTextNodes

really?

in the msdn I found for SelectSingleNode Method:

"...Optional Boolean. True skips all text nodes while searching for the
specified node. False includes text nodes in the search. Default value is
True.

Remarks
Setting the FastSearchSkippingTextNodes parameter to False diminishes
performance because Microsoft Word searches all nodes in a document against
the text contained in the node."

and for SelectNodes Method:

"...Optional Boolean. True skips all text nodes while searching for the
specified node. False includes text nodes in the search. Default value is
False.

Remarks
Setting the FastSearchSkippingTextNodes parameter to True diminishes
performance, because Microsoft Word searches all nodes in a document against
the text contained in the node."

It seems that both do the same things but why is the result in the one
method the opposit of the other?

In my opinion skip would enhance the performance? Or am I wrong?
