这才是我们一开始就需要的东东，这么久才出现，呜呜呜~~~

POST    http://10.0.0.220:9200/shop/_doc/_search

{
    "query": {
        "match": {
            "desc": "我喜欢你"
        }
    },
    "highlight": {
        "pre_tags": ["<span>"],
        "post_tags": ["</span>"],
        "fields": {
            "desc": {}
        }
    }
}

默认情况下，如果不加pre_tags、post_tags，则高亮关键字被<em></em>标签包括，可以采用pre_tags、post_tags进行自定义。
## "pre_tags": ["<span>"]， 开始标签
## "post_tags": ["</span>"]， 结束标签


拓展 - prefix-fuzzy-wildcard
 

prefix根据前缀去查询

POST     http://10.0.0.220:9200/shop/_doc/_search
{
    "query": {
        "prefix": {
            "desc": "哈哈"
        }
    }
}

fuzzy模糊搜索，并不是指的sql的模糊搜索，而是用户在进行搜索的时候的打字错误现象，搜索引擎会自动纠正，然后尝试匹配索引库中的数据。

POST     http://10.0.0.220:9200/shop/_doc/_search
{
  "query": {
    "fuzzy": {
      "desc": "imoov.coom"
    }
  }
}
# 或多字段搜索
{
  "query": {
    "multi_match": {
      "fields": [ "desc", "nickname"],
      "query": "imcoc supor",
      "fuzziness": "AUTO"
    }
  }
}

{
  "query": {
    "multi_match": {
      "fields": [ "desc", "nickname"],
      "query": "演说",
      "fuzziness": "1"
    }
  }
}

wildcard占位符查询

• ？：1个字符

• *：1个或多个字符

  POST     http://10.0.0.220:9200/shop/_doc/_search
  {
    "query": {
      "wildcard": {
        "desc": "*是?"
      }
    }
  }
  {
  	"query": {
      	"wildcard": {
      		"desc": "人*"
      	}
  	}
  }
