Search Tip 11
You have access to the last search results anytime during your browser session, even if you changed to another menu or to eTools.ch 'Mobile Search' in the meantime.
If you wish to delete these temporary session data, just click to 'Reset Session' at the bottom of the page. Otherwise after about 20 minutes idle time, these data will be deleted automatically.
