>                 URL: https://issues.apache.org/jira/browse/LUCENE-10122
>             Project: Lucene - Core
>          Issue Type: Improvement
>          Components: modules/facet
>    Affects Versions: main (9.0)

> We currently use term position of a hardcoded term in a hardcoded field to represent the parent ordinal of each taxonomy label. That is an old way and perhaps could be dated back to the time where doc values didn't exist.
> We probably would want to use NumericDocValues instead given we have spent quite a lot of effort optimizing them.
