Ruslan,

For that you may just add support for callbacks for the structure of the
index, i.e. letting the user implements any B-Tree (or whatever)
derivatives. Some of the most advanced algorithms have patents on them and
you may not want to add the cost of those licenses to everybody. However, if
a developer has a specific need, it could add it to over the kernel.
