Why doesn't the Help topic for open Url tell me how to open a view while passing more than one parameter.

Why doesn't the Help topic for open Url tell me how to open a view while passing more than one parameter.

I need to open an html view, and pass 4 parameters.
 
I see that I can pass one using the example:
 
searchUrl = "#View:Employee_Search?searchParam=" + input.searchEmployee;
openUrl(searchUrl, "same window");

But what about when there is more than one?
