elasticsearch 最佳实践

创建索引

  1. 无mapping 
    创建索引名称为index的索引

    curl -XPUT http://localhost:9200/book
  2. 有mapping

    如果需要定义每个类型的结构映射,创建type名称为user和blogpost的mapping。

    curl -XPUT "http://localhost:9200/book" -d'
    {
    "mappings": {
    "user": { 
      "_all":       { "enabled": false  }, 
      "properties": { 
        "title":    { "type": "string"  }, 
        "name":     { "type": "string"  }, 
        "age":      { "type": "integer" }  
      }
    },
    "blogpost": { 
      "_all":       { "enabled": false  }, 
      "properties": { 
        "id":       { "type": "string"  },
        "title":    { "type": "string"  }, 
        "body":     { "type": "string"  },
        "created":  {
          "type":   "date", 
          "format": "strict_date_optional_time||epoch_millis"
        }
      }
    }
    }
    }'

索引文件

添加四个文档

curl -XPOST http://localhost:9200/book/blogpost/1 -d'
{"body":"美国留给伊拉克的是个烂摊子吗"}
'
curl -XPOST http://localhost:9200/book/blogpost/2 -d'
{"body":"公安部:各地校车将享最高路权"}
'
curl -XPOST http://localhost:9200/book/blogpost/3 -d'
{"body":"中韩渔警冲突调查:韩警平均每天扣1艘中国渔船"}
'
curl -XPOST http://localhost:9200/book/blogpost/4 -d'
{"body":"中国驻洛杉矶领事馆遭亚裔男子枪击 嫌犯已自首"}
'

高亮查询

curl -XPOST http://localhost:9200/book/blogpost/_search  -d'
{
    "query" : { "term" : { "body" : "中国" }},
    "highlight" : {
        "pre_tags" : ["<tag1>", "<tag2>"],
        "post_tags" : ["</tag1>", "</tag2>"],
        "fields" : {
            "content" : {}
        }
    }
}
'
 

删除索引

curl -XDELETE http://localhost:9200/book
