问一个令我困惑的问题

用ED、EM、EM+等搜索下载的时候，假如我的服务器列表里面有若干个可用的服务器，现在我连上的是漫游的ed，那么当我搜索的时候em+等client是否只是搜索漫游的ed上共享的文档，还是连服务器列表里面其它服务器共享的文档也搜索？当开始下载的时候，是否会自动到其它服务器搜索有没有可用的源？
请那位熟悉ED的大大解释一下，thx ！！！！

刚才看了一下ed主页上的文档，里面提到

Server List: As eDonkey runs, it searches all known servers for the files you are currently downloading, having an up to date server-list not only shows eDonkey more working servers to check, but also saves it the time and wasted effort of talking to servers that are no longer functional. A good way to work with the Donkey is to either run with a serverlist updater that gets run each time eDonkey starts (get one from Maurice), or upon starting eDonkey, delete most of the servers that are currently listed, then ask eDonkey to get a new server list by right clicking in the window, selecting 'Get New Serverlist' and entering in the full url for a serverlist (http://ocbmaurice.dyndns.org/pl/slist.pl?download for example).
好像是说会自动搜索所有已知的服务器的，但是还是不确定。
