Is there a way to search a topic?

I am a bit overwhelmed finding what I was looking for in the XCOM Files Topic, but I can't find a way to search only that topic.
Am I blind or does SMF need a plugin like that: http://custom.simplemachines.org/mods/index.php?mod=3627 to make it work?

Also HI! (I actually just registered to make sure searching isn't for registered users only).
I have been really enjoying OpenXcom for years but it's so perfect I never had the urge to make an account and complain about anything. So I will praise everyone involved now

Below the actual search box, there's an option to click called:

Choose a board to search in, or search all

Click on that, and you get check boxes for every forum, clear what you don't want to search.

That helps a lot. Searching a single topic seems impossible then. Well, at least I am not blind
