More info & examples on MAAdaptiveModel ?

Hi all, I am looking for more info or usage examples of MAAdaptiveModel. So far I found the following good resources: * The masters thesis of Lukas Renggli and the impl. of Pier: http://sdmeta.gforge.inria.fr/Teaching/Lille/0910-MetaModelisation/Magritte/... * In the package Magritte-Tests-Model: The test MAAdaptiveModelTest Could someone point me to more resources on MAAdaptiveModel if there are any? Especially the topic searching / building search indexes on MAAdaptiveModel data stored e.g. in mongodb as voyage root would be helpful. -> How is the performance when searching on MAAdaptiveModel values with and without index ? Hints would be nice! Albrecht
