https://stackoverflow.com/search?q=wiki:1 : Shows all community wiki questions.
How would I be able to search for wiki questions that have been made after the change in October,
Users can not mark questions wiki anymore, across the network.
Or at least I think that is when the changed happened (?)
Use the aforementioned wiki:1 plus the created param with the yyyy-mm-dd format and .. for range:
wiki:1 created:2011-10-14..
An example URL version of this would be:
https://meta.stackexchange.com/search?q=wiki%3A1+created%3A2011-10-14..

wiki:1 views:0(the views removes answers from the results list) and then use thenewesttab - the results you want are at the top of the list (in terms of pages), but obviously results that you don't want will still be returned on later pages. – DMA57361 Feb 17 '11 at 12:40
