Sending a Help keyword to the Search in my CHM

[cneff78]

I know about this to show the Search paine:

 

Help.ShowHelp(this, helpProvider.HelpNamespace,

HelpNavigator.Find, "");

 

but I have tried to send keywords via the 4th parameter with no results.

 

What I want to basically be able to do is launch the search paine with my passed in keyword to be displayed and to have a search automatically run.
