This question may sound similar to the following for which solutions are documented:
How can I keep recent files from appearing in Unity?
But my problem is that the Dash (in 10.10) not only lists recently touched files but all files on my mounted partitions (= obviously they are getting indexed automatically).
Is there any way to make Zeitgeist (the responsible application I guesss) exclude certain files/directory hierachies? Or is there any way to disable this kind of indexing completely?
Thanks in advance!
