how can i remove/change the sidebar on my wiki page?

Hi, my blog is pulling the same sidebar as is used on my blog page (the virtue theme seems to format the wiki page using the blog template) - i know how to use css to remove the sidebar, but I would prefer if these page had their own style of sidebar (e.g., with the search wiki pages widget). I installed the Custom Sidebars plugin (also by WPMU DEV) and created a new sidebar that I designated to wiki pages, but it is not displaying. How can I fix this?
