Hi, Have you found such kind of theme?
Looking for similar, but unfortunately can’t find any.
Hala ya Hamza here you go: http://themeforest.net/item/knowledge-base-a-wordpress-wiki-theme/4146138
but this one is also not bad: http://themeforest.net/item/knowledge-base-wiki-faq-wordpress-theme/3434096
you actually need to type in search for: knowledge base, desk support most of these themes and templates have a big search box
