Idf | Overloaded. Implemented as `log(numDocs/(docFreq+1)) + 1`.
Idf (inherited from Similarity) | Overloaded.
LengthNorm | Implemented as `1/sqrt(numTerms)`.
QueryNorm | Implemented as `1/sqrt(sumOfSquaredWeights)`.
SloppyFreq | Implemented as `1 / (distance + 1)`.
Tf | Overloaded. Implemented as `sqrt(freq)`.
Tf (inherited from Similarity) | Overloaded.
