A method and system for finding a conjunctive cluster is disclosed. The method includes identifying a first group of points, identifying a second group of points, drawing a first sample from the first group of points of a first predetermined size and identifying subsets of the first sample. For each subset of the first sample of a second predetermined size the method includes identifying a subgroup of the second group of points that share an intersection with all of the points in the first sample of points, identifying a sub group of said first group of points that share an intersection with a specified number of the points in the subgroup of the second group of points and outputting a third group of points. It should be appreciated that the product of the magnitude of the subgroup of the second group and the magnitude of the subgroup of the first group is maximized.
