hello everybody,
i am a research student. my interest lies in information retrieval in digital repositories especially in document indexing and retrieval.
My basic objective is to improve searching facility provided in digital repository systems especially in DSpace.

As far i know Dspace uses Lucene for document indexing and searching, but i could not find any detailed documentation that help me understand:
how Lucene creates Index?
where it stores its index ?
what technique it uses for searching documents?

one of my colleague is working on "Implementation of multi-faceted searching in DSpace as like DBLP, Flamenco etc"

can anybody help or guide in this regard...
