Robert Tupelo-Schneck commented on SOLR-3818:
---------------------------------------------
This is at least a documentation bug in
https://cwiki.apache.org/confluence/display/solr/The+Term+Vector+Component and
https://wiki.apache.org/solr/TermVectorComponent .
The source code makes it clear: // TODO: this is not TF/IDF by anyone's
definition!
The documentation should make it just as clear, so people don't stumble into
using it incorrectly.
> TermVectorComponent tfidf is not tf/idf by anyone's definition

> tv.tf_idf - Calculates tf*idf for each term. Requires the parameters tv.tf
> and tv.df to be "true". This can be expensive. (not shown in example output)
> {quote}
> But the current computation is tf/docFreq
