It seems like the search bar does only find wiki pages by their names and titles?
A wiki is meant to be seachable through the whole content. So if there is a keyword within the text of a article and I search for this word, I should get it suggested as a search result.
Agreed, thank you Stefan.
I will merge this into https://feedback.youneedawiki.com/10 which will be one of the first tickets I look at after the rewrite is complete.
