Adrien Grand created LUCENE-7524:
------------------------------------
Summary: More detailed explanation of idf
Key: LUCENE-7524
URL: https://issues.apache.org/jira/browse/LUCENE-7524
Project: Lucene - Core
Issue Type: Improvement
Reporter: Adrien Grand
Priority: Minor
The explanations of idf give the docCount and docFreq, but they do not say how
the idf is computed even though the formula is different eg. for
ClassicSimilarity and BM25Similarity. Maybe it would help to put the formula in
the explanations?
