search with 'from:' matches all messages with the word 'from'
I'm running Geary from git mainline on Ubuntu 20.10.
If I search for
from:zanzibar
then I'd expect to see no results, since I have no messages from anyone with that name. Instead, Geary shows me all messages that happen to contain the word 'from'.
Unfortunately this makes 'from:' searches fairly useless at the moment, since they match lots and lots of messages that aren't from the sender I'm searching for.
