Summary: Remove uses of Query.clone()
Key: SOLR-7295
URL: https://issues.apache.org/jira/browse/SOLR-7295
Project: Solr
Issue Type: Bug
Reporter: Yonik Seeley
LUCENE-6369 changed Query.clone to clone deeply.
This is going to represent a performance regression to some who have very large
/ complex queries.
- try to remove any uses of clone() (we assumed shallow clone, and that's no
longer the case)
- attempt to minimize the use of queries that do rewrite (we can only do this
in our own query implementations). A query that rewrites to a different query
will now cause everything to be deep cloned if it's used in a boolean query
anywhere.
