Binary package hint: deskbar-applet
Deskbar applet includes a preference to open a 'Files and Folders Search' as one of the overall quick search options. I have noticed that the search for 'Files and Folders' defaults to the '/home' directory. A good start, but if '/home' is not where many user files are located, or, if others partitions, links or symbolic links are involved, the searches default becomes very limited. The defaults for 'gnome-search-tool' are easily configurable to account for the situation described here (with Config-Editor > gnome-search-tool > select), however it appears that 'deskbar-applet' does not use the 'gnome-search-tool' but 'GnomeSearchHandler' which is uneffected by any config changes made to 'gnome-search-tool'. I have not been able to discover any way to configure the 'Files and Folders' search in the deskbar applet, or to add 'gnome-search-tool' to it. If the default 'Files and Folders' search in the deskbar does not search other files systems (many Ubuntu users will be dual booting with FAT32 data partitions) or follow symbolic links, then this feature of the deskbar becomes almost obsolete and the user needs to open a separate search to find files.
Thnk you for your bug report. I can confirm that.
