Re: Errors and Optimization: re-ordering predicates

> I am torn here. Are other products exploiting the freedom which we give to implementors in this area? Are users of those products complaining? Or are implementors showing restraint by finding a compromise between performance and usability?

eXist does not do much in the way of predicate reordering, currently
we suggest to users to put the most selective predicates first as we
evaluate them from left-to-right. In future, we could do more
intelligent reordering based on index statistics.
