Hi, I'm interested to know if anyone has added (a) the "okapi" aka "BM25" algorithm, (b) a relevance feedback module, or (c) a query expansion modules to Lucene. Or, if there are other types of modifications of similar nature.
We are about to embark in a project to add (a), (b), and (c) above, and would like to know if this has been done. Thanks in advance for your help.
