Search box in Dynamix/Tersus template

Seems like the pages are not excluded from the Search in Tersus/Dynamix template, aparently this one uses a different way to list pages, possibly this:

WP_Query(“s=$s&showposts=-1”);

It is possible to use this plugin that works for this search box? Because it works nicely with the 404-results generator page ??

Thanks
