XF 1.4 Why are URL's not shown in the Bing search


I have installed the Xenforo few days back, I see that my threads can be seen in the google search but no in Bing search. Do i need to do something to make my threads visible in bing search engine ?.

For example here is the example :-
SCCM device collection query for windows 8.1 - If you paste this in google search you can see my forum thread and link. But the same doesn't work in Bing.
