@rmuir > i don't understand this issue. The only purpose of this query is for scoring. If you don't want scores, drop the clause completely. A `FeatureField` provides a useful extension point for learned-sparse retrieval models (see linked issue). These models provide multiple `feature` and `score` pairs. These fields will likely match relevant documents that are not previously matched by other means. A perfectly valid (and powerful) query would be `BooleanQuery` with multiple `SHOULD` clauses containing `FeatureQuery` objects (obviously, with minimum should match > 0). Note that no other field is being queried. Dropping all those clauses would be a `match_all` and not accurately reflect the matching document set. Being able to iterate the entire recall set for matching multiple `FeatureField` values will provide useful insight. -- This is an automated message from the Apache Git Service.
