Thanks. I tried overriding Similarity, returning 1 in lengthNorm and queryNorm and
setSimilarity on IndexSearcher with this.
Query: 1 Found: 1540632
Rank: 1 ID: 8157438 Score: 0.99999994
3.73650457E11 = weight(title:iron in 159395), product of:
7.0507255 = queryWeight(title:iron), product of:
7.0507255 = idf(docFreq=10816)
1.0 = queryNorm
5.2994613E10 = fieldWeight(title:iron in 159395), product of:
1.0 = tf(termFreq(title:iron)=1)
7.0507255 = idf(docFreq=10816)
7.5161928E9 = fieldNorm(field=title, doc=159395)
How do I get rid of QueryWeight, fieldWeight, fieldNorm from the scoring?
I tried modifying TermQuery without much luck.
