Override HTML title tag in views fast search

5.x-2.0, Code, support request, normal, active

I'd like to access values from the views fast search form to set the views fast search HTML title tag (not the drupal title field).
It doesn't seem that I can access those fields with php from within the views header field where I've tried things like:
<?php$name = drupal_get_title();drupal_set_title($form['filter0']['#value'])?>
It also doesn't seem like I can correctly override the $title tag in page.tpl.php where I've tried replacing:
<?php print $head_title ?>
with things like:
<?php print $form['filter0']['#value'] ?>
It's likely my ineptness with PHP and drupal coding that is causing my difficulties.
Would greatly appreciate any clues.
Great module...I'm finding it really, really useful.
Thanks!
