             Summary: Add MultiValued[Int/Long/Float/Double]FieldSource for SortedNumericDocValues
                 Key: LUCENE-7673
                 URL: https://issues.apache.org/jira/browse/LUCENE-7673
             Project: Lucene - Core
          Issue Type: Improvement
            Reporter: Tomás Fernández Löbbe
            Assignee: Tomás Fernández Löbbe


Right now \[Int/Long/Float/Double\]FieldSource can give a {{ValueSource}} view of a {{NumericDocValues}}
field. This Jira is to add MultiValued\[Int/Long/Float/Double\]FieldSource that given a {{SortedNumericSelector.Type}}
can give a {{ValueSource}} view of a {{SortedNumericDocValues}} field
I considered instead of adding new classes an optional selector parameter to the existing
\[Int/Long/Float/Double\]FieldSource, but I think adding different classes makes a cleaner
API and it’s clear that for MultiValued* case, the selector is a mandatory parameter.
