So build the url only to /search/process, and then append the query
string:
<?php echo $this->url(array(
'controller' => 'search',
'action' => 'process',
), null, true) . '?q=' . $this->escape($this->query) ?>
If you need to build a query string out of multiple parameters, use
http_build_query() -- as it looks you've already found.
The url() helper is primarily a mechanism to allow assembling URLs based
on defined routes - which typically do not utilize a query string in
order to perform matching.
