I have found applications like Synapse incredibly useful, but whereas before they seemed to find everything, they now seem to have stopped working for me.
I have tried Synapse, Gnome Do and Kupfer, and with all of them only a very small percentage of my files and folders can be found. (There is no problem with finding applications). Because of this, it seems like some sort of indexing problem.
I have tried uninstalling and reinstalling all the previously mentioned apps, checking their catalogue preferences, reinstalling zeitgeist, and updating the locate database. None of these have made any changes to the search results, which are generally very poor, but occasionally throw up some seemingly random file or folder searches that work.
Please let us know what I can do to make these applications useful again!
