--------------------------------------------
Summary: 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
Priority: Minor
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, close to 5 as
the price value.
