As I mentioned in my earlier reply, you should simply use indomain_split, which 
will give you the expected answer:

?- X :: -9223372036854775808 .. 9223372036854775807,
    X $> 115000000000,
    search([X], 0, input_order, indomain_split, complete, []).
X = 115000000001
Yes (0.00s cpu, solution 1, maybe more)

It's difficult to make a recommendation without knowing what kind of problem you 
are actually trying to solve.
