AbstractA rules analyzer system and method is provided for an enterprise system to evaluate and rank exact and probabilistic search rules for searching a computer database of records according to the efficiency of each search rule. The rules analyzer collects statistics on the performance of each search rule and assigns a priority value for each search rule according to the collected statistics. The priority values are based on the efficiency or precision of each search rule. Thereafter, the rules analyzer ranks the search rules according to the assigned priority.
