	set a combination of parameters on an index

Public Member Functions inherited from faiss::ParameterSpace
size_t	n_combinations () const
	nb of combinations, = product of values sizes

bool	combination_ge (size_t c1, size_t c2) const
	returns whether combinations c1 >= c2 in the tuple sense

std::string	combination_name (size_t cno) const
	get string representation of the combination

void	display () const
	print a description on stdout

ParameterRange &	add_range (const char *name)
