Computes a score factor based on a term or phrase's frequency in a
document. This value is multiplied by the {@link #Idf(Term, Searcher)}
factor for each term in the query and these products are then summed to
form the initial score for a document.
Terms and phrases repeated in a document indicate the topic of the
document, so implementations of this method usually return larger values
when is large, and smaller values when
is small.
The default implementation calls {@link #Tf(float)}.
