Comment 2 for bug 1777219

Just installed LinuxMint 19 from 18.3 (Ubuntu 18.04)
Synapse no longer searches as I type, finding file after a few keystrokes. I must hit enter and then it gives a long list of possible files and not the one I have been referencing frequently.
The Zeitgeist files seem to be updated after each use. .local/share/zeitgeist/
I tried using the zeitgeist folder from 18.3 and no change.
from terminal:
