A computer system and method for cataloging objects, such as requests to purchase an item having a certain configuration, associated with a plurality of attributes describing that object. These attributes are stored in an aggregation component, which is linked to a set of permutation arrays. Each of the permutation arrays indicates an allowable ordering of the plurality of attributes. This object can then be matched with a second object, such as an offer to fill the purchase request, by comparing a plurality of attributes associated with the second object to the attributes describing the first object. Improved searching is effectuated by enabling the matching of objects to be based on the acceptable orderings dictated by the permutation arrays.
