Domain Specific Language
特定领域语言，基于JSON格式的数据查询，查询更灵活，有利于复杂查询
一、普通url路径参数搜索
  • 数据准备
1.建立名字为 shop 的索引
2.手动建立mappings

  1. POST        http://192.168.2.223:9200/shop/_mapping
  2. {
  3.     "properties": {
  4.         "id": {
  5.             "type": "long"
  6.         },
  7.         "age": {
  8.             "type": "integer"
  9.         },
  10.         "username": {
  11.             "type": "keyword"
  12.         },
  13.         "nickname": {
  14.             "type": "text",
  15.             "analyzer": "ik_max_word"
  16.         },
  17.         "money": {
  18.             "type": "float"
  19.         },
  20.         "desc": {
  21.             "type": "text",
  22.             "analyzer": "ik_max_word"

二、检索：

    32.                 }
    33.             }
    34.         ]
    35.     }
    36. }
DSL检索：
  • match_phrase 查询同一个字段中几个词，可以跳过其他词，slop表示可以跳过的最大词数
    • POST http://192.168.2.223:9200/shop/_doc/_search operator 为 “or”表示：字段只要有一个分词就可以查出来，operator 为 “and”表示：字段必须包含分词分出来的所有字段。
      1. {
      2.     "query": {
      3.         "match": {
      4.             "desc": {
      5.                 "query": "周红",
      6.                 "operator": "and"
      7.             }
      8.         }
      9.     },
      10.     "_source": ["id","username","age"]
      11. }
    • POST http://192.168.2.223:9200/shop/_doc/_search
    • ​minimum_should_match: 最低匹配精度，至少有[分词后的词语个数]x百分百，得出一个数据值取整。举个例子：当前属性设置为70，若一个用户查询检索内容分词后有10个词语，那么匹配度按照 10x70%=7，则desc中至少需要有7个词语匹配，就展示；若分词后有8个，则 8x70%=5.6，则desc中至少需要有5个词语匹配，就展示。
    • minimum_should_match 也能设置具体的数字，表示拆分出来的词在一个字段中个数
      1. {
      2.     "query": {
      3.         "match": {
      4.             "desc": {
      5.                 "query": "女友生日送我好玩的xbox游戏机",
      6.                 "minimum_should_match": "60%"
      7.             }
      8.         }
      9.     }
      10. }
  • multi_match 对多个字段进行检索
    • POST http://192.168.2.223:9200/shop/_doc/_search ^10 表示权重，权重，为某个字段设置权重，权重越高，文档相关性得分就越高。通畅来说搜索商品名称要比商品简介的权重更高。
      1. {
      2.     "query": {
      3.         "multi_match": {
      4.             "query": "游戏",
      5.             "fields": [
      6.                 "desc^10","nickname"
      7.             ]
      8.         }
      9.     }
      10. }
  • bool 查询
    • POST http://192.168.2.223:9200/shop/_doc/_search
    • must ：多个条件全部要满足， should：或者的意思，满足一个条件即可，must_not ：除了满足所有条件剩下的数据。
      1. {
      2.     "query": {
      3.         "bool": {
      4.             "must": [
      5.                 {
      6.                     "multi_match": {
      7.                         "query": "游戏",
      8.                         "fields": ["desc","nickname"]
      9.                     }
      10.                 },
      11.                 {
      12.                     "term": {
      13.                         "age": "19"
      14.                     }
      15.                 }
      16.             ]
      17.         }
      18.     }
      19. }
  • post_filter 过滤器
    • POST http://192.168.2.223:9200/shop/_doc/_search
    • 对搜索出来的结果进行数据过滤。不会到es库里去搜，不会去计算文档的相关度分数，所以过滤的性能会比较高，过滤器可以和全文搜索结合在一起使用。
post_filter元素是一个顶层元素，只会对搜索结果进行过滤。不会计算数据的匹配度相关性分数，不会根据分数去排序，query则相反，会计算分数，也会按照分数去排序。
使用场景：
  • ​query：根据用户搜索条件检索匹配记录
  • post_filter：用于查询后，对结果数据的筛选
实操：查询账户金额大于80元，小于等于155.8元的用户
gte：大于等于
lte：小于等于
gt：大于
lt：小于
  1. {
  2.     "query": {
  3.         "match": {
  4.             "sex": "1"
  5.         }
  6.     },
  7.     "post_filter": {
  8.         "range": {
  9.             "money": {
  10.                 "gte": 60,
  11.                 "lte": 155.8
  12.             }
  13.         }
  14.     }
  15. }
  • sort 排序功能
    • POST http://192.168.2.223:9200/shop/_doc/_search 先以money排序再以age排序，注意：只能对整形排序，不能对文本类型排序。
      1. {
      2.     "query": {
      3.         "match": {
      4.             "sex": "1"
      5.         }
      6.     },
      7.     "sort": [
      8.         {
      9.             "money": "asc"
      10.         },
      11.         {
      12.             "age": "asc"
      13.         }
      14.     ]
      15. }
    • 对文本排序
    • 需要对排序字段加一个附加属性，类型选择为keyword

      1. 1.创建索引
      2. POST        /shop2/_mapping
      3. {
      4.     "properties": {

      12.                 "keyword": {
      13.                     "type": "keyword"
      14.                 }
      15.             }
      16.         }
      17.     }
      18. }

      2. {
      3.     "sort": [
      4.         {
      5.             "nickname.keyword": "desc"
      6.         }
      7.     ]
      8. }
  • highlight 关键字高亮显示
    • POST http://192.168.2.223:9200/shop/_doc/_search
      1. {
      2.     "query": {
      3.         "match": {
      4.             "desc": "周红"
      5.         }
      6.     },
      7.     "highlight": {
      8.         "pre_tags": ["<span>"],
      9.         "post_tags": ["</span>"],
      10.         "fields": {
      11.             "desc": {}
      12.         }
      13.     }
      14. }
      结果：默认为em标签，上面设置为自定义的<span>标签，对页面 em/span 标签做一个颜色设置就可以实现高亮显示了。

二、检索：
  • http://192.168.2.223:9200/shop/_search?q=desc:周红&q=age:20
{
"took": 8,
"timed_out": false,
"_shards": {
"total": 3,
"successful": 3,
"skipped": 0,
"failed": 0
},
"hits": {
"total": {
"value": 1,
"relation": "eq"
},
"max_score": 1,
"hits": [
{
"_index": "shop",
"_type": "_doc",
"_id": "1003",
"_score": 1,
"_source": {
"id": 1003,
"age": 20,
"username": "bigFace",
"nickname": "飞翔的巨鹰",
"money": 66.8,
"desc": "周江和导游坐飞机去海外旅游，去了新马泰和欧洲",
"sex": 1,
"birthday": "1996-01-14",
"face": "https://www.zhouhong.com/static/img/index/logo.png"
}
}
]
}
}
 
二、DSL搜索
{
"query": {
"match_all": {}
}
}
{
"query": {
"match_all": {}
},
"_source": ["id","username","age"]
}
{
"query": {
"match_all": {}
},
"_source": ["id","username","age"],
"from": 0,
"size": 5
}
{
"query": {
"match_phrase": {
"desc": {
"query": "今天 车流量",
"slop": 100
}
}
}
}
{
"query": {
"term": {
"desc": "学习"
}
}
}
  • terms 对个关键字查询
{
"query": {
"terms": {
"desc": ["学习","周红","周江"]
}
}
}
{
"query": {
"match": {
"desc": "周红"
}
},
"_source": ["id","username","age"]
}
{
"query": {
"match": {
"desc": {
"query": "周红",
"operator": "and"
}
}
},
"_source": ["id","username","age"]
}
    • POST http://192.168.2.223:9200/shop/_doc/_search
    • ​minimum_should_match: 最低匹配精度，至少有[分词后的词语个数]x百分百，得出一个数据值取整。举个例子：当前属性设置为70，若一个用户查询检索内容分词后有10个词语，那么匹配度按照 10x70%=7，则desc中至少需要有7个词语匹配，就展示；若分词后有8个，则 8x70%=5.6，则desc中至少需要有5个词语匹配，就展示。
    • minimum_should_match 也能设置具体的数字，表示拆分出来的词在一个字段中个数
{
"query": {
"match": {
"desc": {
"query": "女友生日送我好玩的xbox游戏机",
"minimum_should_match": "60%"
}
}
}
}
{
"query": {
"ids": {
"type": "_doc",
"values": ["1001","1005","1006"]
}
},
"_source": ["id","username","desc"]
}
  • multi_match 对多个字段进行检索
    • POST http://192.168.2.223:9200/shop/_doc/_search ^10 表示权重，权重，为某个字段设置权重，权重越高，文档相关性得分就越高。通畅来说搜索商品名称要比商品简介的权重更高。
{
"query": {
"multi_match": {
"query": "游戏",
"fields": [
"desc^10","nickname"
]
}
}
}
{
"query": {
"bool": {
"must": [
{
"multi_match": {
"query": "游戏",
"fields": ["desc","nickname"]
}
},
{
"term": {
"age": "19"
}
}
]
}
}
}
 
  • post_filter 过滤器
    • POST http://192.168.2.223:9200/shop/_doc/_search
    • 对搜索出来的结果进行数据过滤。不会到es库里去搜，不会去计算文档的相关度分数，所以过滤的性能会比较高，过滤器可以和全文搜索结合在一起使用。
post_filter元素是一个顶层元素，只会对搜索结果进行过滤。不会计算数据的匹配度相关性分数，不会根据分数去排序，query则相反，会计算分数，也会按照分数去排序。
使用场景：
  • ​query：根据用户搜索条件检索匹配记录
  • post_filter：用于查询后，对结果数据的筛选
实操：查询账户金额大于80元，小于等于155.8元的用户
gte：大于等于
lte：小于等于
gt：大于
lt：小于
{
"query": {
"match": {
"sex": "1"
}
},
"post_filter": {
"range": {
"money": {
"gte": 60,
"lte": 155.8
}
}
}
}
 
{
"query": {
"match": {
"sex": "1"
}
},
"sort": [
{
"money": "asc"
},
{
"age": "asc"
}
]
}
    • 对文本排序
    • 需要对排序字段加一个附加属性，类型选择为keyword
1.创建索引
POST /shop2/_mapping
{
"properties": {
"id": {
"type": "long"
},
"nickname": {
"type": "text",
"analyzer": "ik_max_word",
"fields": {
"keyword": {
"type": "keyword"
}
}
}
}
}
 
2.插入数据
POST /shop2/_doc
{
"id": 1001,
"nickname": "美丽的风景"
}
{
"id": 1002,
"nickname": "漂亮的小哥哥"
}
{
"id": 1003,
"nickname": "飞翔的巨鹰"
}
{
"id": 1004,
"nickname": "完美的天空"
}
{
"id": 1005,
"nickname": "广阔的海域"
}

 
3.排序 POST http://192.168.2.223:9200/shop2/_doc/_search
{
"sort": [
{
"nickname.keyword": "desc"
}
]
}

{
"query": {
"exists": {
"field": "desc"
}
}
}
 
{
"query": {
"match": {
"desc": "周红"
}
},
"highlight": {
"pre_tags": ["<span>"],
"post_tags": ["</span>"],
"fields": {
"desc": {}
}
}
}
结果：默认为em标签，上面设置为自定义的<span>标签，对页面 em/span 标签做一个颜色设置就可以实现高亮显示了。
