I'm referring to this page, as found on all other vBulletin forums: https://mygaming.co.za/forum/search.php
On sites like Carb and MyBB, it's under a button called "Advanced Search", and the only way I was able to find it, is by using the same page URL as found on these sites. I can only see "Google Search", which is quite useless for specific site searches.
Or am I missing it somewhere on the page?
