23、ElasticSearch 7.3 实战：RestHighLevelClient Java api实现match_all、ids、match、term、multi_match、bool、filter、sort等不同的搜索方式

1、数据准备

首先创建book索引

PUT /book/
{
  "settings": {
    "number_of_shards": 1,
    "number_of_replicas": 0
  },
  "mappings": {
    "properties": {
      "name": {
        "type": "text",
        "analyzer": "ik_max_word",
        "search_analyzer": "ik_smart"
      },
      "description": {
        "type": "text",
        "analyzer": "ik_max_word",
        "search_analyzer": "ik_smart"
      },
      "studymodel": {
        "type": "keyword"
      },
      "price": {
        "type": "double"
      },
      "timestamp": {
        "type": "date",
        "format": "yyyy-MM-dd HH:mm:ss||yyyy-MM-dd||epoch_millis"
      },
      "pic": {
        "type": "text",
        "index": false
      }
    }
  }
}

添加测试数据

PUT /book/_doc/1
{
  "name": "Bootstrap开发",
  "description": "Bootstrap是一个非常流行的开发框架。此开发框架可以帮助不擅长css页面开发的程序人员轻松的实现一个css，不受浏览器限制的精美界面css效果。",
  "studymodel": "201002",
  "price": 38.6,
  "timestamp": "2019-08-25 19:11:35",
  "pic": "group1/M00/00/00/wKhlQFs6RCeAY0pHAAJx5ZjNDEM428.jpg",
  "tags": [
    "bootstrap",
    "dev"
  ]
}

PUT /book/_doc/2
{
  "name": "java编程思想",
  "description": "java语言是世界第一编程语言，在软件开发领域使用人数最多。",
  "studymodel": "201001",
  "price": 68.6,
  "timestamp": "2019-08-25 19:11:35",
  "pic": "group1/M00/00/00/wKhlQFs6RCeAY0pHAAJx5ZjNDEM428.jpg",
  "tags": [
    "java",
    "dev"
  ]
}

PUT /book/_doc/3
{
  "name": "spring开发基础",
  "description": "spring 在java领域非常流行，java程序员都在用。",
  "studymodel": "201001",
  "price": 88.6,
  "timestamp": "2019-08-24 19:11:35",
  "pic": "group1/M00/00/00/wKhlQFs6RCeAY0pHAAJx5ZjNDEM428.jpg",
  "tags": [
    "spring",
    "java"
  ]
}

2、match_all搜索

match_all用来搜索全部记录，先回顾下语法

GET /book/_search
{
  "query": {
    "match_all": {}
  }
}

返回

{
  "took" : 0,
  "timed_out" : false,
  "_shards" : {
    "total" : 1,
    "successful" : 1,
    "skipped" : 0,
    "failed" : 0
  },
  "hits" : {
    "total" : {
      "value" : 3,
      "relation" : "eq"
    },
    "max_score" : 1.0,
    "hits" : [
      {
        "_index" : "book",
        "_type" : "_doc",
        "_id" : "1",
        "_score" : 1.0,
        "_source" : {
          "name" : "Bootstrap开发",
          "description" : "Bootstrap是一个非常流行的开发框架。此开发框架可以帮助不擅长css页面开发的程序人员轻松的实现一个css，不受浏览器限制的精美界面css效果。",
          "studymodel" : "201002",
          "price" : 38.6,
          "timestamp" : "2019-08-25 19:11:35",
          "pic" : "group1/M00/00/00/wKhlQFs6RCeAY0pHAAJx5ZjNDEM428.jpg",
          "tags" : [
            "bootstrap",
            "dev"
          ]
        }
      },
      {
        "_index" : "book",
        "_type" : "_doc",
        "_id" : "2",
        "_score" : 1.0,
        "_source" : {
          "name" : "java编程思想",
          "description" : "java语言是世界第一编程语言，在软件开发领域使用人数最多。",
          "studymodel" : "201001",
          "price" : 68.6,
          "timestamp" : "2019-08-25 19:11:35",
          "pic" : "group1/M00/00/00/wKhlQFs6RCeAY0pHAAJx5ZjNDEM428.jpg",
          "tags" : [
            "java",
            "dev"
          ]
        }
      },
      {
        "_index" : "book",
        "_type" : "_doc",
        "_id" : "3",
        "_score" : 1.0,
        "_source" : {
          "name" : "spring开发基础",
          "description" : "spring 在java领域非常流行，java程序员都在用。",
          "studymodel" : "201001",
          "price" : 88.6,
          "timestamp" : "2019-08-24 19:11:35",
          "pic" : "group1/M00/00/00/wKhlQFs6RCeAY0pHAAJx5ZjNDEM428.jpg",
          "tags" : [
            "spring",
            "java"
          ]
        }
      }
    ]
  }
}

Java代码

    @Test
    public void testSearchAll() throws IOException {

        //1构建搜索请求
        SearchRequest searchRequest = new SearchRequest("book");
        SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
        searchSourceBuilder.query(QueryBuilders.matchAllQuery());

        //获取某些字段
//        searchSourceBuilder.fetchSource(new String[]{"name"}, new String[]{});

        searchRequest.source(searchSourceBuilder);

        //2执行搜索
        SearchResponse searchResponse = client.search(searchRequest, RequestOptions.DEFAULT);

        //3获取结果
        SearchHits hits = searchResponse.getHits();

        //数据数据
        SearchHit[] searchHits = hits.getHits();
        System.out.println("--------------------------");
        for (SearchHit hit : searchHits) {

            String id = hit.getId();
            float score = hit.getScore();
            Map<String, Object> sourceAsMap = hit.getSourceAsMap();
            String name = (String) sourceAsMap.get("name");
            String description = (String) sourceAsMap.get("description");
            Double price = (Double) sourceAsMap.get("price");
            System.out.println("name:" + name);
            System.out.println("description:" + description);
            System.out.println("price:" + price);
            System.out.println("==========================");

        }
    }

返回结果

3、IDs搜索

IDs用来搜索指定id的记录，先回顾下语法

GET /book/_search
{
  "query": {
    "ids": {
      "values": [1,4,100]
    }
  }
}

只有id为1才存在数据，id为4，id为100均无数据

{
  "took" : 2,
  "timed_out" : false,
  "_shards" : {
    "total" : 1,
    "successful" : 1,
    "skipped" : 0,
    "failed" : 0
  },
  "hits" : {
    "total" : {
      "value" : 1,
      "relation" : "eq"
    },
    "max_score" : 1.0,
    "hits" : [
      {
        "_index" : "book",
        "_type" : "_doc",
        "_id" : "1",
        "_score" : 1.0,
        "_source" : {
          "name" : "Bootstrap开发",
          "description" : "Bootstrap是一个非常流行的开发框架。此开发框架可以帮助不擅长css页面开发的程序人员轻松的实现一个css，不受浏览器限制的精美界面css效果。",
          "studymodel" : "201002",
          "price" : 38.6,
          "timestamp" : "2019-08-25 19:11:35",
          "pic" : "group1/M00/00/00/wKhlQFs6RCeAY0pHAAJx5ZjNDEM428.jpg",
          "tags" : [
            "bootstrap",
            "dev"
          ]
        }
      }
    ]
  }
}

Java代码

    //ids搜索
    @Test
    public void testSearchIds() throws IOException {

        //1构建搜索请求
        SearchRequest searchRequest = new SearchRequest("book");
        SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
        searchSourceBuilder.query(QueryBuilders.idsQuery().addIds("1","4","100"));

        searchRequest.source(searchSourceBuilder);
        //2执行搜索
        SearchResponse searchResponse = client.search(searchRequest, RequestOptions.DEFAULT);
        //3获取结果
        SearchHits hits = searchResponse.getHits();

        //数据数据
        SearchHit[] searchHits = hits.getHits();
        System.out.println("--------------------------");
        for (SearchHit hit : searchHits) {
            String id = hit.getId();
            float score = hit.getScore();
            Map<String, Object> sourceAsMap = hit.getSourceAsMap();
            String name = (String) sourceAsMap.get("name");
            String description = (String) sourceAsMap.get("description");
            Double price = (Double) sourceAsMap.get("price");
            System.out.println("id:" + id);
            System.out.println("name:" + name);
            System.out.println("description:" + description);
            System.out.println("price:" + price);
            System.out.println("==========================");
        }
    }

返回结果

4、match搜索

match就是普通的分词搜索，先回顾下语法

GET /book/_search
{
  "query": {
    "match": {
      "description": "java程序员"
    }
  }
}

返回结果

{
  "took" : 88,
  "timed_out" : false,
  "_shards" : {
    "total" : 1,
    "successful" : 1,
    "skipped" : 0,
    "failed" : 0
  },
  "hits" : {
    "total" : {
      "value" : 2,
      "relation" : "eq"
    },
    "max_score" : 1.9788694,
    "hits" : [
      {
        "_index" : "book",
        "_type" : "_doc",
        "_id" : "3",
        "_score" : 1.9788694,
        "_source" : {
          "name" : "spring开发基础",
          "description" : "spring 在java领域非常流行，java程序员都在用。",
          "studymodel" : "201001",
          "price" : 88.6,
          "timestamp" : "2019-08-24 19:11:35",
          "pic" : "group1/M00/00/00/wKhlQFs6RCeAY0pHAAJx5ZjNDEM428.jpg",
          "tags" : [
            "spring",
            "java"
          ]
        }
      },
      {
        "_index" : "book",
        "_type" : "_doc",
        "_id" : "2",
        "_score" : 0.51124346,
        "_source" : {
          "name" : "java编程思想",
          "description" : "java语言是世界第一编程语言，在软件开发领域使用人数最多。",
          "studymodel" : "201001",
          "price" : 68.6,
          "timestamp" : "2019-08-25 19:11:35",
          "pic" : "group1/M00/00/00/wKhlQFs6RCeAY0pHAAJx5ZjNDEM428.jpg",
          "tags" : [
            "java",
            "dev"
          ]
        }
      }
    ]
  }
}

Java代码

    //match搜索  普通搜索
    @Test
    public void testSearchMatch() throws IOException {

        //1构建搜索请求
        SearchRequest searchRequest = new SearchRequest("book");
        SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
        searchSourceBuilder.query(QueryBuilders.matchQuery("description", "java程序员"));
        searchRequest.source(searchSourceBuilder);
        //2执行搜索
        SearchResponse searchResponse = client.search(searchRequest, RequestOptions.DEFAULT);
        //3获取结果
        SearchHits hits = searchResponse.getHits();
        //数据数据
        SearchHit[] searchHits = hits.getHits();
        System.out.println("--------------------------");
        for (SearchHit hit : searchHits) {
            String id = hit.getId();
            float score = hit.getScore();
            Map<String, Object> sourceAsMap = hit.getSourceAsMap();
            String name = (String) sourceAsMap.get("name");
            String description = (String) sourceAsMap.get("description");
            Double price = (Double) sourceAsMap.get("price");
            System.out.println("id:" + id);
            System.out.println("name:" + name);
            System.out.println("description:" + description);
            System.out.println("price:" + price);
            System.out.println("==========================");
        }
    }

返回结果

5、term搜索

不会对搜索关键词进行分词，代表精确匹配

GET /book/_search
{
  "query": {
    "term": {
      "description": "java程序员"
    }
  }
}

无结果返回，原因description已被分词，无java程序员这个单独词汇

{
  "took" : 0,
  "timed_out" : false,
  "_shards" : {
    "total" : 1,
    "successful" : 1,
    "skipped" : 0,
    "failed" : 0
  },
  "hits" : {
    "total" : {
      "value" : 0,
      "relation" : "eq"
    },
    "max_score" : null,
    "hits" : [ ]
  }
}

Java代码

    //term 搜索
    @Test
    public void testSearchTerm() throws IOException {
        //1构建搜索请求
        SearchRequest searchRequest = new SearchRequest("book");
        SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
        searchSourceBuilder.query(QueryBuilders.termQuery("description", "java程序员"));
        searchRequest.source(searchSourceBuilder);
        //2执行搜索
        SearchResponse searchResponse = client.search(searchRequest, RequestOptions.DEFAULT);
        //3获取结果
        SearchHits hits = searchResponse.getHits();
        //数据数据
        SearchHit[] searchHits = hits.getHits();
        System.out.println("--------------------------");
        for (SearchHit hit : searchHits) {
            String id = hit.getId();
            float score = hit.getScore();
            Map<String, Object> sourceAsMap = hit.getSourceAsMap();
            String name = (String) sourceAsMap.get("name");
            String description = (String) sourceAsMap.get("description");
            Double price = (Double) sourceAsMap.get("price");
            System.out.println("id:" + id);
            System.out.println("name:" + name);
            System.out.println("description:" + description);
            System.out.println("price:" + price);
            System.out.println("==========================");
        }
    }

同样无返回结果。

6、multi_match多字段搜索

同时匹配多个字段进行搜索，先回顾下语法

GET /book/_search
{
  "query": {
    "multi_match": {
      "query": "java程序员",
      "fields": [
        "name",
        "description"
      ]
    }
  }
}

将name，description中包含关键词的结果返回

{
  "took" : 54,
  "timed_out" : false,
  "_shards" : {
    "total" : 1,
    "successful" : 1,
    "skipped" : 0,
    "failed" : 0
  },
  "hits" : {
    "total" : {
      "value" : 2,
      "relation" : "eq"
    },
    "max_score" : 1.9788694,
    "hits" : [
      {
        "_index" : "book",
        "_type" : "_doc",
        "_id" : "3",
        "_score" : 1.9788694,
        "_source" : {
          "name" : "spring开发基础",
          "description" : "spring 在java领域非常流行，java程序员都在用。",
          "studymodel" : "201001",
          "price" : 88.6,
          "timestamp" : "2019-08-24 19:11:35",
          "pic" : "group1/M00/00/00/wKhlQFs6RCeAY0pHAAJx5ZjNDEM428.jpg",
          "tags" : [
            "spring",
            "java"
          ]
        }
      },
      {
        "_index" : "book",
        "_type" : "_doc",
        "_id" : "2",
        "_score" : 0.9331132,
        "_source" : {
          "name" : "java编程思想",
          "description" : "java语言是世界第一编程语言，在软件开发领域使用人数最多。",
          "studymodel" : "201001",
          "price" : 68.6,
          "timestamp" : "2019-08-25 19:11:35",
          "pic" : "group1/M00/00/00/wKhlQFs6RCeAY0pHAAJx5ZjNDEM428.jpg",
          "tags" : [
            "java",
            "dev"
          ]
        }
      }
    ]
  }
}

Java代码

    //multi_match搜索  多字段搜索
    @Test
    public void testSearchMultiMatch() throws IOException {
        //1构建搜索请求
        SearchRequest searchRequest = new SearchRequest("book");
        SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
        searchSourceBuilder.query(QueryBuilders.multiMatchQuery("java程序员","name","description"));
        searchRequest.source(searchSourceBuilder);
        //2执行搜索
        SearchResponse searchResponse = client.search(searchRequest, RequestOptions.DEFAULT);
        //3获取结果
        SearchHits hits = searchResponse.getHits();
        //数据数据
        SearchHit[] searchHits = hits.getHits();
        System.out.println("--------------------------");
        for (SearchHit hit : searchHits) {
            String id = hit.getId();
            float score = hit.getScore();
            Map<String, Object> sourceAsMap = hit.getSourceAsMap();
            String name = (String) sourceAsMap.get("name");
            String description = (String) sourceAsMap.get("description");
            Double price = (Double) sourceAsMap.get("price");
            System.out.println("id:" + id);
            System.out.println("name:" + name);
            System.out.println("description:" + description);
            System.out.println("price:" + price);
            System.out.println("==========================");
        }
    }

返回结果

7、bool搜索

bool搜索类似于数据库中的and or关键词，先回顾下语法，搜索name、description必须包含java程序员，或者studymodel包含201001的数据

GET /book/_search
{
  "query": {
    "bool": {
      "must": [

8、filter过滤

对搜索进行过滤，注意与query进行区别，先回顾下语法，搜索name、description必须包含java程序员，或者studymodel包含201001，price在50至70范围内

GET /book/_search
{
  "query": {
    "bool": {
      "must": [
        {
          "multi_match": {
            "query": "java程序员",
            "fields": [
              "name",
              "description"
            ]
          }
        }
      ],
      "should": [
        {
          "match": {
            "studymodel": "201001"
          }
        }
      ],
      "filter": {
        "range": {
          "price": {
            "gte": 50,

  "query": {
    "bool": {
      "must": [

              "name",
              "description"
            ]
          }
        }
      ],
      "should": [

          }
        }
      ],
      "filter": {
        "range": {
          "price": {
            "gte": 50,
            "lte": 90
          }
        }
      }
    }
  },
  "sort": [

10、总结

1、 在实际的应用过程要注意灵活变通，搜索方式方法不要一成不变，要思考为什么这种方式能够搜索出来结果，还要思考搜索结果的正确与否；
2、 在上面的学习过程中，应该也能发现规律，Java代码中构建搜索请求与rest风格的语法及其类似，包括其搜索方式、代码层级所以在实际应用中，要先在kibana中完善搜索代码，只要kibana中能够搜索出来，Java代码一般来说也能行，这样能够缩短代码调试的时间；
