OK, I think I'm missing something big time... Can someone point me to the documentation of the explain? Thanks a lot, M

Hi, Anyone knows what is exactly Similarity.tf()? I understood it's term frequency on a document. Still, when I'm searching for a string a document contains, and the Explain().toString() shows tf=0. search string: "SubTitle:(Without)" matching documents: 3 0: 1.0: "Dropping Out," Drifting Off, Being Excluded: Becoming Somebody Without School 0.0 = fieldWeight(SubTitle:without in 0), product of: 0.0 = tf(termFreq(SubTitle:without)=0) 7.214108 = idf(docFreq=3) 0.5 = fieldNorm(field=SubTitle, doc=0) 1: 0.625: "I Have A Life" Bride's Guide: Plan The Wedding You've Always Wanted--without Losing Your Mind 0.0 = fieldWeight(SubTitle:without in 1), product of: 0.0 = tf(termFreq(SubTitle:without)=0) 7.214108 = idf(docFreq=3) 7.5161928E9 = fieldNorm(field=SubTitle, doc=1) 2: 0.625: 1 Microsoft Way: A Cookbook to Breaking Bill Gates Windows Monopoly Without Breaking Windows 0.0 = fieldWeight(SubTitle:without in 2), product of: 0.0 = tf(termFreq(SubTitle:without)=0) 7.214108 = idf(docFreq=3) 7.5161928E9 = fieldNorm(field=SubTitle, doc=2)
