Hello. I've not used eXist and Xindice carefully.
But, eXist employs Numbering Scheme for XML indexing. Numering Scheme is a method to count nodes with begin and end position in an XML document. Numbering Scheme makes it possible to detect nodes' ancestor-descendant relationships with nodes' numbers alone. Then, queries including Regular Path Expressions like, "Book//person", "//Book//name" are speeded up. Because traversals of all of possible nodes are not needed. By constructing B+-tree, "Book" nodes' list and "person" nodes' list are searched efficently. And joined with Structural Join Algorithms. However, Updates of Nubering Scheme have not been studied yet.
