search/6 inside bagof/3?

Dear Eclipse team,

In a constraint program, I would like to know the number of backtracks when 
searching for all solutions. The predicate search/6 seems to be the choice to 
learn the number of backtracks. However, when I use search/6 inside bagof/3 

bagof(X,search(X,0,input_order,indomain_min,complete,[backtrack(B)]),Bag)

I get only one solution, while 

bagof(X,search(X,0,input_order,indomain_min,complete,[]),Bag)

would give me all the solutions with no information on backtracks.

How can I look for all solutions and also count backtracks?

Thanks,
Zeynep
