Abstract
Methods are described to simultaneously apply conjugates of equality, range, and in-list predicates. A first set of methods are described for the simultaneous application of equality predicates. A second set of methods are described for the simultaneous application of a mixture of range and equality predicates. A third method is described for the simultaneous applying a mixture of in-list predicates. The described methods allow for quick evaluation of complex predicates as they efficiently implement the computation done per record, while maintaining the same execution time irrespective of the number of fields.
