....ordering corresponds to a depth first traversal of the potential search space. The obvious main drawback of our approach is the necessarily exhaustive search space generation. For this, a solution avoiding the demand to first span the whole space is sketched in the next section. 4 Related Work [18] explains how the complexity of optimizing queries with many selection predicates is comparable to join sequence optimization in relational databases. Because there are many rules describing commutativity and selection pushing, every selection predicate may be arranged at nearly every place in a ....
