[Elecraft] Search on archives ?

[DR]

Ok...I'm sure this is going to be a bonehead question but I can't figure out 
HOW to search the Elecraft archives.  I hate to post a question I have 
regarding the Control Board on the K2 that I'm sure has been answered in 
previous posts but I cannot figure out how to use a search on the archives 
found here:
