I was trying to add a feature in the admin so that cart owner can track what all searches have been done by customers
I am putting the search keywords and number of products found for those keywords

I went to

includes\modules\pages\advanced_search_result\header_php.php
and I can see that variable has the keyword $_GET['keyword'] but how do I get the numeber of results found for this. Can someone tell me the variable?
Thanks
