I never use the Finder to find networked drives ever and I am very old Mac user (since 8.6). In OS X I always used the Finder menu item 'Go', 'connect to Server or command button+k (keyboard shortcut). Then just manually putting in Network drive's IP address via SMB or AFP.
Can you search a network drive with finder in mavericks, or will it still not work like in mountain lion? I have a synology ds413j and it's frustrating to have to always go to the dsm page and use file station to find a file.
