-----------------------------------
Summary: Query Metadata Aggregator
Key: LUCENE-8919
URL: https://issues.apache.org/jira/browse/LUCENE-8919
Project: Lucene - Core
Issue Type: Improvement
Reporter: Atri Sharma
It would be good if there was a mechanism to allow aggregation of metadata for
queries (eg, number of clauses, types of clauses, terms involved etc). This is
particularly useful for complex queries with multiple levels of nesting and a
high degree of branching. This should help debug query performance issues and
draw patterns in case a query is misbehaving. With the QueryVisitor being
present, this should be doable.
