Elasticsearch 7 报错:

Root mapping definition has unsupported parameters:  [product : {properties={title={type=text}}}

原因:elasticsearch7默认不在支持指定索引类型,默认索引类型是_doc,如果想改变,则配置include_type_name: true 即可(这个没有测试,官方文档说的,无论是否可行,建议不要这么做,因为elasticsearch8后就不在提供该字段)。官方文档:https://www.elastic.co/guide/en/elasticsearch/reference/current/removal-of-types.html

下面的指令在ES6没问题:

PUT test_index
{
  "settings":{
    "number_of_shards":1, 
    "number_of_replicas":0     
  },
  "mappings":{
    "product": {
      "properties": {
        "title": {"type": "text"}
      }
    }
  }
}

*****product为指定索引类型

ES7必须改为:

PUT test_index
{
  "settings":{
    "number_of_shards":1, 
    "number_of_replicas":0     
  },
  "mappings":{
      "properties": {
        "title": {"type": "text"}
    }
  }
}
