Having a hard time using this site, especially after being use to TGB.

How do I search in this site.  Especially inside threads?

There are lots of long ones with lots of information but I can't see a way to search individual threads.

Most of the forums I had frequented have tools to search/download threads, or am I just missing something?

Same question here.  How do I search inside a thread so I know if my question was already answered???  I even tried using Google site search, but the url for each thread is too long for Google (it cuts off the end of the address and searches the entire Web site instead.)
