json - 使用 json 文件在 elasticsearch 中定义映射

Question

我尝试使用 json 文件来定义每个索引的默认映射。这就是我正在尝试做的事情:

/usr/share/elasticsearch/config/default-mapping.json

{
    "item": {
        "properties": {
            "uuid": {"type": "string", "store": "yes", "index": "no"},
            "title": {"type": "string", "store": "yes", "boost": 5,
                      "index": "analyzed", "analyzer": "english"},
            "description": {"type": "string", "store": "yes", "boost": 3,
                            "index": "analyzed", "analyzer": "english"},
}

当我尝试查询我的index_test elasticsearch 索引时，我得到:

curl -XGET 'http://...:9200/index_test/_mapping'
{"index_test":{"mappings":{}}}

我使用了此处找到的文档。

您可以创建index template使用索引的默认配置(索引设置、映射等)。

1. 为此，请将 default-mapping.json 文件的内容更改为某些内容像:

   {
       "template_1" : {
           "template" : "*",
           "mappings" : {
               "type" : {
                   "properties" : {
                       "uuid" : {
                           "type" : "string",
                           "store" : "yes",
                           "index" : "no"
                       },
                       "title" : {
                           "type" : "string",
                           "store" : "yes",
                           "boost" : 5,
                           "index" : "analyzed",
                           "analyzer" : "english"
                       },
                       "description" : {
                           "type" : "string",
                           "store" : "yes",
                           "boost" : 3,
                           "index" : "analyzed",
                           "analyzer" : "english"
                       }
                   }
               }
           }
       }
   }
   

2. 将 default-mapping.json 文件移至/usr/share/elasticsearch/config/templates 目录

3. 创建新索引

   POST /newindex
   

4. 新创建索引的映射:

   {
       "newindex" : {
           "mappings" : {
               "type" : {
                   "properties" : {
                       "description" : {
                           "type" : "string",
                           "boost" : 3,
                           "store" : true,
                           "analyzer" : "english"
                       },
                       "title" : {
                           "type" : "string",
                           "boost" : 5,
                           "store" : true,
                           "analyzer" : "english"
                       },
                       "uuid" : {
                           "type" : "string",
                           "index" : "no",
                           "store" : true
                       }
                   }
               }
           }
       }
   }
   

希望这对您有帮助。
