解決策

観測されたエラーは、 elasticsearch.yml valuesで設定されたデフォルト値であるようです。 I.e. デフォルトの最大許容限界は1024ですが、クエリ文字列フィールドは6511です。詳しくは、こちらをご覧ください - https://www.elastic.co/guide/en/elasticsearch/reference/current/breaking-changes-7.0.html#_limiting_the_number_of_auto_expanded_fields
また、同じようにelasticsearch.ymlファイルの indices.query.bool.max_clause_count の制限を変更すると、より効果的です。
