In this release we will change the max_clause_count from the default value of 1024 to 4096. This change should prevent this error from happening under specific circumstances:
{"type":"too_many_clauses","reason":"maxClauseCount is set to 1024"}
The indices.query.bool.max_clause_count setting can not be set during runtime, for that reason we’ve configured it in /etc/elasticsearch/elasticsearch.yml.
Changes will be deployed over the course of this week.
