Reverse search allows you to find reciprocal exchanges more easily. When you activate the "Reverse Search" filter in your search, you will see all members who added your location to their preferred destination.
If, for example, I check "Reverse Search" when I search for Rome and live in Paris: I will see all the homes of members living in Rome that added Paris (or "France" or "Europe" for example) in their preferred destinations.

But you can not search for members who have registered a particular destination. For example, I can not search for members who have added Grenoble as their preferred destination. I can only see the members who have registered a destination that corresponds to my own location.
