ElasticSearch 7.x 默認不在支持指定索引類型
在elasticsearch7.x上執行：

put es_test {"settings":{ "number_of_shards" : 3, "number_of_replicas" : 0 }, "mappings":{ "books":{ "properties":{ "title":{"type":"text"},"name":{"type":"text","index":false},"publish_date":{"type":"date","index":false}, "price":{"type":"double"}, "number":{"type":"object","dynamic":true}}}} }

執行結果則會出錯：Root mapping definition has unsupported parameters

{"error": {"root_cause": [{"type": "mapper_parsing_exception","reason": "Root mapping definition has unsupported parameters: [books : {properties={number={dynamic=true, type=object}, price={type=double}, name={index=false, type=text}, title={type=text}, publish_date={index=false, type=date}}}]"}],"type": "mapper_parsing_exception","reason": "Failed to parse mapping [_doc]: Root mapping definition has unsupported parameters: [books : {properties={number={dynamic=true, type=object}, price={type=double}, name={index=false, type=text}, title={type=text}, publish_date={index=false, type=date}}}]","caused_by": {"type": "mapper_parsing_exception","reason": "Root mapping definition has unsupported parameters: [books : {properties={number={dynamic=true, type=object}, price={type=double}, name={index=false, type=text}, title={type=text}, publish_date={index=false, type=date}}}]"}},"status": 400 }

如果在6.x上執行，則會正常執行

{"acknowledged" : true }

出現這個的原因是，elasticsearch7默認不在支持指定索引類型，默認索引類型是_doc，如果想改變，則配置include_type_name: true 即可(這個沒有測試，官方文檔說的，無論是否可行，建議不要這么做，因為elasticsearch8后就不在提供該字段)。官方文檔：https://www.elastic.co/guide/en/elasticsearch/reference/current/removal-of-types.html

所以在Elasticsearch7中應該這么創建索引

put /test {"settings":{"number_of_shards":3,"number_of_replicas":2},"mappings":{"properties":{"id":{"type":"long"},"name":{"type":"text","analyzer":"ik_smart"},"text":{"type":"text","analyzer":"ik_max_word"}}}}put /test1 {"settings":{"number_of_shards":3,"number_of_replicas":2},"mappings":{"properties":{"id":{"type":"long"},"name":{"type":"text"},"text":{"type":"text"}}}}
