Subject SpanQuery scoring seems different
Date Wed, 02 Apr 2008 07:15:53 GMT
Hi all,

It seems that SpanNearQuery doesn't consider the boosting of the nested terms:

  1.3333334 = (MATCH) weight(spanNear([content2MBM:morgan^4.0,
content2MBM:stanley^4.0], 2, true) in 11976), product of:
    2.0 = queryWeight(spanNear([content2MBM:morgan^4.0,
content2MBM:stanley^4.0], 2, true)), product of:
      2.0 = idf(content2MBM: morgan=13 stanley=4)
      1.0 = queryNorm
    0.6666667 = (MATCH) fieldWeight(content2MBM:spanNear([morgan^4.0,
stanley^4.0], 2, true) in 11976), product of:
      0.33333334 = tf(phraseFreq=0.33333334)
      2.0 = idf(content2MBM: morgan=13 stanley=4)
      1.0 = fieldNorm(field=content2MBM, doc=11976)


with a BooleanQuery the boosting is included in the score calculation

    ....
    4.0 = (MATCH) weight(content2MBM:stanley^4.0 in 11976), product of:
      4.0 = queryWeight(content2MBM:stanley^4.0), product of:
        4.0 = boost                 /* This Line is what I want */
        1.0 = idf(docFreq=4, numDocs=45619)
        1.0 = queryNorm
      1.0 = (MATCH) fieldWeight(content2MBM:stanley in 11976), product of:
        1.0 = tf(termFreq(content2MBM:stanley)=1)
        1.0 = idf(docFreq=4, numDocs=45619)
        1.0 = fieldNorm(field=content2MBM, doc=11976)

I previously assume boost is calculated in all queries.
I am using 2.3.0.
