elasticsearch之高亮查询

准备数据

PUT zhifou/doc/4
{
  "name":"石头",
  "age":29,
  "from":"gu",
  "desc":"粗中有细，狐假虎威",
  "tags":["粗", "大","猛"]
}

 

默认高亮显示  highlight

GET zhifou/doc/_search
{
  "query": {
    "match": {
      "name": "石头"
    }
  },
  "highlight": {
    "fields": {
      "name": {}
    }
  }
}

 

 

结果如下：

{
  "took" : 1,
  "timed_out" : false,
  "_shards" : {
    "total" : 5,
    "successful" : 5,
    "skipped" : 0,
    "failed" : 0
  },
  "hits" : {
    "total" : 1,
    "max_score" : 1.5098256,
    "hits" : [
      {
        "_index" : "zhifou",
        "_type" : "doc",
        "_id" : "4",
        "_score" : 1.5098256,
        "_source" : {
          "name" : "石头",
          "age" : 29,
          "from" : "gu",
          "desc" : "粗中有细，狐假虎威",
          "tags" : [
            "粗",
            "大",
            "猛"
          ]
        },
        "highlight" : {
          "name" : [
            "<em>石</em><em>头</em>"    #此处高亮显示
          ]
        }
      }
    ]
  }
}

 

 

自定义高亮显示

GET zhifou/chengyuan/_search
{
  "query": {
    "match": {
      "from": "gu"
    }
  },
  "highlight": {
    "pre_tags": "<b class='key' style='color:red'>",
    "post_tags": "</b>",
    "fields": {
      "from": {}
    }
  }
}

需要注意的是：自定义标签中属性或样式中的逗号一律用英文状态的单引号表示，应该与外部elasticsearch语法的双引号区分开。
