In one embodiment, a system includes a format block configured to receive a key, at least one rule, and rule formatting information. The rule can have one or more dimensions. The format block can be further configured to extract each of the dimensions from the at least one rule. The system can further include a plurality of dimension matching engines (DME). Each DME can be configured to receive the key and a corresponding formatted dimension, and process the key and the corresponding dimension for returning a match or nomatch. The system can further include a post processing block configured to analyze the matches or no matches returned from the DMEs and return a response based on the returned matches or nomatches.
