---------------------------------------
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.
