> Lucene employs the Vector Space Model (VSM) to rank documents, which compares
> unfavorably to state of the art algorithms, such as BM25. Moreover, the architecture
is
> tailored specically to VSM, which makes the addition of new ranking functions a non-
> trivial task.
> This project aims to bring state of the art ranking methods to Lucene and to implement
a
> query architecture with pluggable ranking functions.
