I'm premium user and I have some offline notebooks. Also I have a number of saved searches. These searches addressed to those offline notebooks. If my phone with fully synced offline notebooks and turned on offline seach becomes offline, saved searches wouldn't work. I understand "offline search" term as "evernote has offline search function which is the same as online search function, but can work in offline mode with offline notebooks". Evernote is some sort of platform for GTD. In this case search speed and availability of search function are critical for me. Can someone write down some links, where I can read and fully understand a mechanism of offline search? I want an official description of offline search function.
