We have an hidden setting called `index.queries.cache.term_queries` that disables caching of term queries in the query cache. Though term queries are not cached in the Lucene UsageTrackingQueryCachingPolicy since version 6.5. This makes the es policy useless but also makes it impossible to re-enable caching for term queries. This change appeared in Lucene 6.5 so this setting is no-op since version 5.4 of Elasticsearch The change in this PR removes the setting and the custom policy.

Good catch! This setting was undocumented on purpose, we do not allow users to configure what queries can be cached in general. So I don't think there is anything to do besides removing the setting and |

The change in this PR removes the setting and the custom policy.
For 7 I think it's ok to remove the setting but I don't know what to do for 5.6 and 6.x. Re-enabling the ability to cache term queries is tricky and would require to fork the Lucene UsageTrackingQueryCachingPolicy which is why I marked this PR with the discuss label.
