Update: Hmm so they changed it recently again and it's not possible to search whole categories such as Electronics, you have to fraction it further to Sound&Vision, etc. Before 2009 it was possible to search everything no problem. Ebay is becoming like Facebook - worse and worse with every update. Good tip is to search for - (or,and,of,is,I,if,at,where,when,you,why,how,new,used) - Include the brackets and tick "Title and description" in Advanced search. It returned over 8.5 mil items or 13k auctions which granted is far from all, but you can always modify it to your needs.
