I'm not sure how to interpret the result of the toString method of

Explanation. I'm trying to see the values of each component of the

Default Similarity formula for a particular query and a doc. Given

below is a sample of my Explanation output. Many thanks if anyone could

help explain some of the values or direct me to a place that does so.

Explanation = 0.683103 = product of:

1.7077575 = sum of:

0.184242 = weight(Contents:x in 78), product of:

0.13565542 = queryWeight(Contents:x), product of:

2.509232 = idf(docFreq=85)

0.054062527 = queryNorm

1.3581617 = fieldWeight(Contents:x in 78), product of:

1.7320508 = tf(termFreq(Contents:x)=3)

2.509232 = idf(docFreq=85)

0.3125 = fieldNorm(field=Contents, doc=78)

0.184242 = weight(Contents:x in 78), product of:

0.13565542 = queryWeight(Contents:x), product of:

2.509232 = idf(docFreq=85)

0.054062527 = queryNorm

1.3581617 = fieldWeight(Contents:x in 78), product of:

1.7320508 = tf(termFreq(Contents:x)=3)

2.509232 = idf(docFreq=85)

0.3125 = fieldNorm(field=Contents, doc=78)

0.26218253 = weight(Contents:y in 78), product of:

0.16182467 = queryWeight(Contents:y), product of:

2.9932873 = idf(docFreq=52)

0.054062527 = queryNorm

1.6201642 = fieldWeight(Contents:y in 78), product of:

1.7320508 = tf(termFreq(Contents:y)=3)

2.9932873 = idf(docFreq=52)

0.3125 = fieldNorm(field=Contents, doc=78)
