In some of my group's usage of lucene over large document collections,
we have split the documents across several machines. This has lead to a
concern of whether the inverse document frequency was appropriate, since
the score seems to be dependant on the partioning of documents over
indexing hosts. We have not formulated an experiment to determine if it
seriously effects our results, though it has been discussed.
If someone could elaborate how BM25 or some DFR algorithm would differ
from what (TF/IDF) is implemented in lucene, I would be willing to help
translate that into java as an indexing/searching option . . .
