A while ago I requested a list of the "most frequently searched for terms for which no Wikipedia articles are returned". This would allow the community to than create redirect or new pages as appropriate and help address the "zero results rate" of about 30%.
While we are still waiting for this data I have recently come across a list of the most frequently clicked on redlinks on En WP produced by Andrew West https://en.wikipedia.org/wiki/User:West.andrew.g/Popular_redlinks Many of these can be reasonably addressed with a redirect as the issue is often capitals.
Do anyone know where things are at with respect to producing the list of most search for terms that return nothing?
