• search id:11, got it cached in query results.
• add docs, commit
• it triggers cache regeneration, this query is executed per every shard. However, their scores are local only.
• search id:11 again, got cache hit, retrieve local only scores. Ignore exact stats, even they are properly distributed via GET_TERM_STATS

the seed to reproduce -ea -Dtestcase=TestExactSharedStatsCache -Dtests.method=test -Dtests.seed=EF21F7455842423F -Dtests.multiplier=2 -Dtests.slow=true -Dtests.locale=de-GR -Dtests.timezone=Etc/GMT-11 -Dtests.asserts=true -Dtests.file.encoding=UTF-8, note the test was fixed by https://git-wip-us.apache.org/repos/asf?p=lucene-solr.git;h=7c44862 . So, to reproduce, it needs to be rolled back.
