You learn something new every day and, on this occasion, it's a very helpful tip from Brindabella
The Search facility in ActiveBoard (generally - not just on this forum) is pretty naff.
It is better to use Google and specify that you want the search on this forum e.g. put this into the Google search bar and see how many results you get compared to the ActiveBoard Search!

I got 153 results compared to only 9 using the ActiveBoard search.
