Hard to locate older topics (search?)

Now that the new forums are getting busy with lots of topics spread over many categories, I am running into a worsening problem - finding older topics/posts! Once the latest/greatest four scroll off the home page, you are really out of luck. What compounds this problem is the topics can overlap somewhat, and posts could potentially be placed in several categories, its up to the original poster's preference. I am not a mind reader, so sometimes I miss the category and have to go looking around, and with slow internet sometimes, its becoming an issue to find things.

 I do not see any obvious search feature in the forums? I think a search box would solve the problem.
