Searching seems to be broken

Im trying to search for the xpander tutorial, and when typing xpander I get 1 result, as expected. Though if I then click on that result, I get a list of all results, and it says "search results for ‘’ with 909 results. So if i do CTRL+F and then xpander, hit search it takes me to the link to the xpander tutorial, but when I click on that it takes me to the sonic academy world cup comp :confused:
