Self-indexing (and traditional indexing) algorithms - Implementations and advice to share?

Solution
Here is a nice introductory presentation on self-indexing (PDF).
Problem
As part of a research project I'm currently looking for open-source implementations of self-indexing algorithms, i.e. a compressed form of the traditional inverted index yielding nice characteristics such as faster lookup and/or less consumed space. Do you know of any open-source implementations of self-indexing algorithms? Do you have other interesting takes on indexing algorithms or data structures to share? All languages and license variants are welcome.
