I am running Gnome Shell and I do not like Zeitgeist indexing all my files. This makes the overview search in gnome-shell very slow. I do not want the overview to search recent files, so I installed activity log manager to prevent zeitgeist's logging activity. I configured the log manager as below.
But even after adding every folder, the files keep appearing in the overview under Recent Items. Is there any other software or tweak which will instruct zeitgeist to search only applications installed in my system and not my recent files.
As far as I understand the Recent Items have nothing to do with Zeitgeist.
You could try the instructions made in the answer of this question.
I removed and re-installed Zeitgeist Activity Log Manager. This now appears to be working, but there are still images / documents in Dash history that should have been excluded.
I think Unity may auto-start zeitgeist-daemon, and that the blacklists' stopped working intermittently (after updates?) over the last two walso eeks.
I also tried Zeitgeist Activity Journal, and manually removed entries that should not have been logged (for last 2 weeks). The software is quite cumbersome, but will hopefully improve soon.
hint: in ThumbView mode - use drop-down button (top-right), enable Erase Mode
This may have fixed issue, but I have NOT identifies any root-cause ..
Use GTK+ Recent Files Scrubber for deleting things appearing in gtk-open-dialogues via blacklists.
