https://en.wikipedia.org/wiki/SMART_Information_Retrieval_System

The current TFIDF model uses natural TF and IDF for computing TFIDF. The idea is to try various transformation like logarithmic, augmented,boolean etc. before computing the vectors.

More about this - http://www.cs.odu.edu/~jbollen/IR04/readings/article1-29-03.pdf and https://nlp.stanford.edu/IR-book/pdf/06vect.pdf

Will send a PR tomorrow.
