Semantich Search Cas Indexer   

Hi,
i'm working with UIMA and i must create an index for my application.
UIMA SDK includes a semantic search engine that i can use to build a search index.
Semantich Search Cas Indexer is a Cas Consumer to write the CAS data to a Juru index.
In the package, downoaded from IBM's alphaWorks, there is only Semantic Search CAS indexer's descriptor that is locate in:
examples/descriptors/cas_consumer/SemanticSearchCasIndexer.xml

Is it ossible have a source code of Semantich Search CAS indexer?

Is it possible have a source code of Juru index?

I hope in an answer.
Thank to every body.
