how do I call a plugin when 'new posts' is clicked but not when a search is performed

[30et]

Hi Lynne
I'm not sure how to use the do variable.
When I perform a search the resulting URL is /search.php?searchid=3734120 which doesn't have a 'do' querystring.

To get this do variable I tried a couple ways ..
I created a plugin and wrote

print_r ($_GET);

and this writes the querystring on the page, which is

[searchid] => 3734147

And I added the following in the 'search_resultlist' template

<vb:if condition="$_GET['do'] == 'getnew'">Hello there!</vb:if>

But that didn't display the text 'Hello there!'

Maybe I'm placing the vb code in the wrong place or writing it incorrectly? I don't understand how to access the $_GET['do'] variable when its not in the URL.
