A computerized method of reducing complexity of data analysis including an inverse search process over a plurality of multimedia content elements mapped to points in a d-dimensional space, and by that improves search, advertising and database analysis efficiency. The computerized method comprises the stages: (i) mapping the points to core-set points, comprising a weighted set of points that represents the points according to predefined geometrical relationships, such that the number of the core-set points is substantially smaller than the number of the points; (ii) inversely projecting the core-set points to receive weighted multimedia content elements, such that weighting is carried out in relation to the geometrical relationships among the core-set points; and (iii) applying at least one inverse search algorithm to the weighted multimedia content elements.
