> Key: LUCENE-9384
> URL: https://issues.apache.org/jira/browse/LUCENE-9384
> Project: Lucene - Core
> Issue Type: Task

> Priority: Minor
> Fix For: 8.7

> Field sort optimization implemented in LUCENE-9280 is based on an assumption that if a numeric field is indexed with both doc values and points, the *same data* is stored in these points and doc values. While there is a plan in LUCENE-9334 to enforce this consistency from Lucene 9.0, there is nothing in Lucene 8.x to enforce this assumption.
>
> Thus in order to backport the sort optimization to 8.x, we need to make a user to explicitly opt in for it. This could be done by either:
> * introducing a special SortField (e.g. DocValuesPointSortField) that will use optimization
> * introduce a bool parameter to a SortField which when true will indicate that the sort optimization should be enabled (e.g. SortField("my_field", SortField.Type.LONG, true))
