The searchbar in general needs a complete overhaul. I mean have you ever seen a searchbar on any forum that limited the number of search results to 50? It is just unheard of. Not to mention only searching thread titles and not the content. But the admins have their hands full and features like that can't get added overnight.
You just have to learn how to use the searchbar well. Use fewer words if you want to find something. For example if you are looking for 177 volkl walls, don't fucking search "177 volkl walls". Search "177" or "volkl" or "walls". I don't think there is any problem with the searchbar other then user error.
