Scoring problem with MultiPhraseQuery?
I'm using MultiPhraseQuery to implement a fuzzy phrase query.
E.g. user enters "blue lorry" and I expand 'blue' to 'turquoise', and 'glue' and
'lorry' to 'truck', 'van', 'lory' and 'lorrie'. I can then construct a
MultiPhraseQuery with those lists of terms.
The search works correctly but the score is always the total number of terms (N)
that I put into the MultiPhraseQuery (N=8 in this example)!
I've tried using a boost of 1/N but the boost appears to be ignored.
I can't think of a reason why this should be intentional beheviour so I assume
there's a bug.
I'm using Lucene 3.0.
Thanks,
Mike Cawson

More likely to be a bug in your code rather than in lucene. I suggest
you post the smallest possible self-contained program or test case
that demonstrates the problem.
