%iFind.Rank.TFIDF
hidden class %iFind.Rank.TFIDF extends %iFind.Rank.Abstract
This class provides the default ranking algorithm, using a TF component based on term frequency ([frequency] / [word count]) and a smoothed Inverse Document Frequency component ( log(1 + ([total doc count] / [document frequency])) ).
When there are multiple matching words for a search leaf node, the "best" one's score will be used for that node. Wen the search leaf node refers to a multi-word string (positional / entity), the score will be multiplied with the log of the word count + 1 to express the fact that this is a more strict search criterion.
