Hi,

I found the following papers of potential interest to Lucene community:

* http://www2008.org/papers/pdf/p387-zhangA.pdf "Performance of Compressed Inverted List Caching in Search Engines", discusses a new compression algorithm for inverted indexes, PForDelta, and its performance benefits over other well-known algorithms.

* http://www2008.org/papers/pdf/p1213-ding.pdf "Using Graphics Processors for High-Performance IR Query Processing", discusses the application of GPU for posting list decompression and intersection.
