   No, it can't.   
      
   It causes the entire post database to be downloaded, all posts, so that   
   it can scan them. This is a large load on a server, not polite.   
      
   On imap, TB does a search on the cache. It can download missing posts   
   and store them on the cache. Or, it can ask the server to do the search   
   internally.   
      
   I have not tried imap without local cache. However, I also use Alpine,   
   an ancient mail client in text mode, which does not keep a cache, and   
   body text search if the server doesn't support search is not supported,   
   except with a trick, and then it is very slow.

   Oh, I could do that pulling the messages from the local leafnode, it   
   would run faster than from the remote.
