Hi all, I have two questions related to the Lucene ranking. 1) Does anyone know how the posting lists (term -> doc1 doc2 doc3) from the index are sorted? It is used a TFxIDF value, the boost value or none to sort documents (doc1 doc2 doc3)? Does Lucene compute the ranking for all the documents in the posting lists or only part? 2) Does anyone know how to add more ranking features to the ranking function of Lucene (eg. Pagerank, BM25)? Extending the DefaultSimilarity class from Lucene is insufficient to achieve this. It is only prepared to change the TFxIDF function. Thanks in advance.
