Peilin Yang commented on LUCENE-7466:
-------------------------------------
Thanks for pointing this out.
For the test cases, since all of the variations extend from the base Axiomatic
class and all the constructors all basically the same (except AxiomaticF3EXP
where a queryLen is needed that is why there is a QL test) so I just pick F2EXP
to test.
Does this make any sense to you?

> Key: LUCENE-7466
> URL: https://issues.apache.org/jira/browse/LUCENE-7466
> Project: Lucene - Core
> Issue Type: Improvement
> Components: core/search
> Affects Versions: master (7.0)
> Reporter: Peilin Yang
> Assignee: Tommaso Teofili
> Labels: patch
>
> Add axiomatic similarity approaches to the similarity family.
> More details can be found at http://dl.acm.org/citation.cfm?id=1076116 and
> https://www.eecis.udel.edu/~hfang/pubs/sigir05-axiom.pdf
> There are in total six similarity models. All of them are based on BM25,
> Pivoted Document Length Normalization or Language Model with Dirichlet prior.
> We think it is worthy to add the models as part of Lucene.
