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. -- This message is automatically generated by JIRA.
