Shawn Heisey commented on LUCENE-5699:
--------------------------------------
bq. This patch is including all the mentioned features. It is contains some
really ugly modification because of the auto-formating in eclipse and auto
organizing imports.
Eclipse will not automatically reformat or organize imports unless you have
changed its default configuration to turn these options on. Can you re-do your
changes and save without these options turned on?
It also looks like the some of the new formatting is using a different format
specification than the one that comes with Lucene/Solr. The correct
specification is automatically used when you run "ant eclipse" and import the
project into eclipse. Some of it looks correct, which is very odd.

> Now the classifiers can return only the "best matching" classes. If somebody
> want it to use more complex tasks he need to modify these classes for get
> second and third results too. If it is possible to return a list and it is
> not a lot resource why we dont do that? (We iterate a list so also.)
> The Bayes classifier get too small return values, and there were a bug with
> the zero floats. It was fixed with logarithmic. It would be nice to scale the
> class scores sum vlue to one, and then we coud compare two documents return
> score and relevance. (If we dont do this the wordcount in the test documents
> affected the result score.)
> With bulletpoints:
> * In the Bayes classification normalized score values, and return with result
> lists.
> * In the KNN classifier possibility to return a result list.
> * Make the ClassificationResult Comparable for list sorting.
