What I should do is follow my own advice!
The advice I have given to puzzlers who ask is to give the absolute minimum number of words and preferably one which could be unique to that puzzle..
For instance if it's a Ford Fabmobile Super-Dooper Mk XII you're looking for, don't even include 'Ford' or anything other than just 'Fabmobile'. That way it will come up with just one result (or 2 if it's been re-posted!!)
There's nothing wrong with the Search facility at all in my opinion; it's down to what you search for and how the facility is used...
