A method and system for storing a plurality of filter rules in a computer system is disclosed. The plurality of filter rules uses at least one range of values in at least one dimension. The method and system include separating a portion of the plurality of filter rules into a plurality of pure subsets of filter rules. Each of the plurality of pure subsets of filter rules includes at least one of the plurality of filter rules. The method and system also include combining a portion of the plurality of pure subsets of filter rules to provide a combined subset and determining whether an efficiency of utilizing the plurality of filter rules is improved by combining the portion of the plurality of pure subsets of filter rules. The method and system further includes storing the plurality of filter rules including storing the portion of the plurality of subsets of filter rules as the combined subset if the efficiency of searching the plurality of filter rules is improved.
