> Key: LUCENE-8606
> URL: https://issues.apache.org/jira/browse/LUCENE-8606
> Project: Lucene - Core
> Issue Type: Improvement
> Reporter: Christian Ziech
> Priority: Major
>
> Right now the ConstantScoreWeigth used by the ConstantScoreQuery is not adding the details of the wrapped query to the explanation.
> {code}
> if (exists) {
> return Explanation.match(score, getQuery().toString() + (score == 1f ? "" : "^" + score));
> } else {
> return Explanation.noMatch(getQuery().toString() + " doesn't match id " + doc);
> }
> {code}
> This is kind of inconvenient as it makes it kind of hard to figure out which term finally really matched when one e.g. puts a BooleanQuery into the FILTER clause of another BooleanQuery.
