Excuse me, may I ask something about the spatial search in CGAL in the following?

http://www.cgal.org/Manual/3.3/doc_html/cgal_manual/Spatial_searching/Chapter_main.html

In the spatial search examples in the above links, the search is only based on point type

May I ask if it is possible to use user defined type in the search?

e.g.
 

if I have the following struct


typedef CGAL::Simple_cartesian<double> Rep_class;
typedef Rep_class::Point_3 Point;
typedef CGAL::Vector_3<Rep_class > Vector;

struct SamplePoint
{
     Point sample_point;
     Vector  surface_normal;
};


Then, is it possible to search by using the the information of a sample_point,
then after it has searched a SamplePoint object by using the information of the sample_point,
return the surface_normal of that searched object ?
May I ask if it is possible to use the search structure to do that?

Hope you know what I mean. Thank you very much.
