Our in-house search takes 100 years to crawl the site and I can't get any third-party stuff like Google to work here for some unknown reason. Honestly I'm kinda hoping Talkspot implements a better Search widget at some point, but maybe I'll think of something else. In the meantime our menu system is pretty boss now, give that a look.
If you really need to search the site for something, there is a halfassed solution. Go to Google, type your search term, then after it type "site:platoscavern2.talkspot.com", which will cause it to search only this site.
