----------------------------------------------
Hi Tommaso,
the answer is yes, but I don't have any estimation at the moment, and to be
honest I have not even worked on that yet( issue creation apart) .
I will update the issue when I have some better estimation on when I will start!
Of course anyone could contribute ideas/patch in the meantime !
> Document Classifiers to handle numeric fields
> ---------------------------------------------
>
> Key: LUCENE-7116
> URL: https://issues.apache.org/jira/browse/LUCENE-7116
> Project: Lucene - Core
> Issue Type: Improvement
> Components: modules/classification
> Affects Versions: 5.5
> Reporter: Alessandro Benedetti
> Assignee: Tommaso Teofili
> Priority: Minor
> Labels: classification, classifier
>
> DocumentClassifiers should handle numeric fields.
> Knn Document Classifier should be able to handle function queries( like the
> distance from the numeric value in input) as boost factors on top of the MLT
> boolean query.
> Investigations will follow with tentative design and patch
> e.g.
> input document has price:5
> We can classify the document based on all the ones in the index, in proximity
> to 5 as the price value.
