Version 7.8 (457453) Direct; Editor: 62.1.7539 (b406110), running on Mac OS Mojave 10.14.2.
For some weeks, searching has been failing, and I have had repeatedly to Recreate Full Text Index Search (from OPT Help > Troubleshooting). I have almost 18000 notes including 2000 in local notebooks, so it takes 12-24 hours to recreate. During this time, searching works fine on the Web and iOS versions (though not across the local notebooks, of course).
I have eventually discovered that the index is lost if I quit Evernote, so I am having to leave it open 24x7 on my iMac, which I don't really want to do. Besides, I forget sometimes, and close the program by accident.
The lack of a reliable searching mechanism defeats the whole object of choosing Evernote over its rivals: if I can't search for something I put there months ago, that is not tagged, and is not in the notebook I thought it might be, it is not very useful!
(Secondary problem: despite being a Premium member, I can find no way to raise a Support Ticket!)
Does anyone else have this problem? Is there a fix, please?
