Hello Robert!
Yes, fuzzySearch() works correctly!

This function uses an octree to find a cell that is *close* to the searched 
one. Then it uses the mesh connectivity to find the cell that contains the 
given point.

It is just some kind of speed optimization that gives a good initial guess to 
the find() function. Using this strategy, only 1 to 3 elements are usually 
tested to find the good one...

So, if you are looking for an element use the find() function and not only 
fuzzySearch().

Stephane.
