------------------------------------
Summary: Never cache GlobalOrdinalQuery
Key: LUCENE-8062
URL: https://issues.apache.org/jira/browse/LUCENE-8062
Project: Lucene - Core
Issue Type: Improvement
Reporter: Jim Ferenczi
Priority: Minor
GlobalOrdinalsQuery holds a possibly large bitset of global ordinals that can
pollute the query cache because the size of the query is not accounted in the
memory usage of the cache.
Moreover two instances of this query must share the same top reader context to
be considered equal so they are not the ideal candidate for segment level
caching.
