（14）ElasticSearch 基本查询（中文查询）

　　1、准备数据

PUT /lib
{
    "settings":{
        "number_of_shards":3,
        "number_of_replicas":0
    },
    "mappings":{
        "user":{
            "properties":{
                "name":{
                    "type":"text",
                    "analyzer":"ik_max_word"
                },
                "address":{
                    "type":"text",
                    "analyzer":"ik_max_word"
                },
                "age":{
                    "type":"integer"
                },
                "interests":{
                    "type":"text",
                    "analyzer":"ik_max_word"
                },
                "birthday":{
                    "type":"date"
                }
            }
        }
    }
}

PUT /lib/user/1
{
    "name":"赵六",
    "address":"黑龙江省铁岭",
    "age":50,
    "birthday":"1970-12-12",
    "interests":"喜欢喝酒，锻炼，说相声"
}

PUT /lib/user/2
{
    "name":"赵明",
    "address":"北京海淀区清河",
    "age":20,
    "birthday":"1998-10-12",
    "interests":"喜欢喝酒，锻炼，唱歌"
}

PUT /lib/user/3
{
    "name":"lisi",
    "address":"北京海淀区清河",
    "age":23,
    "birthday":"1998-10-12",
    "interests":"喜欢喝酒，锻炼，唱歌"
}

PUT /lib/user/4
{
    "name":"王五",
    "address":"北京海淀区清河",
    "age":26,
    "birthday":"1995-10-12",

}

PUT /lib/user/5

    "name":"张三",
    "address":"北京海淀区清河",
    "age":29,
    "birthday":"1988-10-12",
    "interests":"喜欢摄影，听音乐，跳舞"
}

　　2、操作演示

　　1）查询出name中带有赵字的，赵明和赵六的文档

GET /lib/user/_search/
{
    "query":{
        "term":{"name":"赵"}
    }
}

GET /lib/user/_search/
{
    "query":{
        "match":{"name":"赵"}
    }
}

　　2）查询出interests中含有喝酒或者唱歌的文档

GET /lib/user/_search/
{
    "query":{
        "terms":{
            "interests":["喝酒","唱歌"]
        }
    }
}

　　3）查询出interests中含有喝酒或者唱歌的文档，从下标为0开始，只查询出两个

GET /lib/user/_search/
{
    "from":0,
    "size":2,
    "query":{
        "terms":{
            "interests":["喝酒","唱歌"]
        }
    }
}

　　4）查询出interests中含有喝酒或者唱歌的文档，并且 显示版本号

GET /lib/user/_search/
{
    "version":true,
    "query":{
        "terms":{
            "interests":["喝酒","唱歌"]
        }
    }
}

　　5）查询出name含有赵或者含有六的文档，会查询出赵明和赵六，因为match会分词。

GET /lib/user/_search/
{
    "query":{
        "match":{
            "name":"赵六"
        }
    }
}

　　6）查询出age是20的文档，结果显示赵明，数字型不分词。

GET /lib/user/_search/
{
    "query":{
        "match":{
            "age":20
        }
    }
}

　　7）查询出所有文档

GET /lib/user/_search/
{
    "query":{
        "match_all":{}
    }
}

　　8）多字段查询multi_match，字段name或者interests中含有唱歌的都会查询出来

GET /lib/user/_search/
{
    "query":{
        "multi_match":{
            "query":"唱歌",
            "fields":["interests","name"]
        }
    }
}

　　9）短语匹配查询match_phrase，关键字作为一个短语，必须完全匹配，如下，必须含有“锻炼，说相声”这个短语才能查到

GET /lib/user/_search/
{
    "query":{
        "match_phrase":{
            "interests":"锻炼，说相声"
        }
    }
}

　　10）指定返回的字段 _source，如下，返回的结果中只有 address和 name

GET /lib/user/_search/
{
    "_source":["address","name"],
    "query":{
        "match":{
            "interests":"唱歌"
        }
    }
}

　　11）前缀匹配查询 match_phrase_prefix，查询name，以“赵”开头

GET /lib/user/_search/
{
    "query":{
        "match_phrase_prefix":{
            "name":{"query":"赵"}
        }
    }
}
