I have had this same problem since October - many updates ago. Have worked with Evernote support several times but still offline search does not work. There have been several upgrades which support says should fix the issue but nothing has worked. Specifically: I have a group of lists with check boxes. I have a search that returns the list if any of the check boxes are not checked. Works great when I have a connection but returns nothing when offline. Anyone know why this should not work with a premium account? Very frustrating. Thanks.
