The Wikipedia App does not have a real search result page. If you enter a search query into the field named "Search Wikipedia" it will only show pages which title match the query string.
If the user have a type error in there or change the words (e.g. "Seat Ibiza" to "Ibiza Seat") the search seems to doesn't find any search results, however the mobile web and web search will find the article (e.g. "Seat Ibiza").
Request: Add a real search result page (the API still exist) to show after the user hit the Enter equivalent key (not show "No search result").
Version: Stable
