Geek Speak

naive but hopeful query

hi, is there any way to search for a specific thread in the Zone - eg. by topic, or date? The only way I know is to keep pressing the 'earlier' button & inspecting - not practical for stuff posted months ago (esp. with slow connections..) - I am looking for a discussion (in 'space') on air-breathing rocket engines (scramjets), a few months ago. - any advice appreciated, thanks.
