>                 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.
