When performing a web search, Domino will display "no documents found". On a web site you might want to hide this from the user. There are other ways, but the simplest is to override the H2 HTML tag with a CSS Style. Set the H2 Tag to the same color as the background and voila, "no documents found" disappears. You could also set the font pixel size to 1px so that when a user highlights the page,it is not seen as well.
I have seen many technical and difficult solutions,yet this has to be the simplest solution ever!.
Credit goes to Andrew Cornes of Domino source who came up with the idea the other day while on project with me.
Code
<style>
HR { font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 1px; color: ###background color###}
</style>
