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.
gnome-shell
and then talk about search in Dash. In GS, Dash is the launcher on left hand side and in Unity dash is what you get by pressing Super key. Please update your question
