             Summary: CoveringQuery to use multi-valued field length as minimum match
                 Key: LUCENE-8613
                 URL: https://issues.apache.org/jira/browse/LUCENE-8613
             Project: Lucene - Core
          Issue Type: Improvement
    Affects Versions: 7.5
            Reporter: Tristan Stevens


Currently CoveringQuery uses a long field's value for the minimumMatch for each document.
There are use cases where this value may be derived from the length of a multi-valued field (including docValues).
This request is to support an alternative constructor and implementation for CoveringQuery to take a field name that can be used for the per-document minimum match value.
