Elasticsearch-文档查询

数据准备

查询

• 简单查询

  mall/goods/1
  

  

• 条件查询

  GET mall/goods/_search?q=b_name: "如何"
  

  

复杂查询

• 匹配查询

  GET mall/goods/_search
  {
    "query": {
      "match": {
        "b_name": "怎样征服美丽少女"
      }
    }
  }
  

  

• 查询的结果只展示指定的字段

  GET mall/goods/_search
  {
    "query": {
      "match": {
        "b_name": "怎样征服美丽少女"
      }
    },
    "_source": ["b_name","author"]
  }
  

  

• 排序

  GET mall/goods/_search
  {
    "query": {
      "match": {
        "b_name": "怎样征服美丽少女"
      }
    },
    "_source": ["b_name","author","price"],
    "sort": [
      {
        "price": {
          "order": "desc"
        }
      }
    ]
  }
  

  

• 分页

  GET mall/goods/_search
  {
    "query": {
      "match": {
        "b_name": "怎样征服美丽少女"
      }
    },
    "_source": ["b_name","author","price"],
    "sort": [
      {
        "price": {
          "order": "desc"
        }
      }
    ],
    "from": 0,
    "size": 2
  }
  

  

• 布尔查询

  bool：
  must，should，must_not，filter

  • 必须同时匹配多个条件查询，相当于and

    GET mall/goods/_search
    {
      "query": {
        "bool": {
          "must": [
            {
              "match": {
                "b_name": "美丽少女"
              }
            },
            {
              "match": {
                "price": "28"
              }
            }
          ]
        }
      }
    }
    

    

  • 只要符合多个条件中的一个条件，相当于or

    GET mall/goods/_search
    {
      "query": {
        "bool": {
          "should": [
            {
              "match": {
                "b_name": "美丽少女"
              }
            },
            {
              "match": {
                "price": "28"
              }
            }
          ]
        }
      }
    }
    

    

  • 非查询，not

    GET mall/goods/_search
    {
      "query": {
        "bool": {
          "must_not": [
            {
              "match": {
                "b_name": "美丽少女"
              }
            },
            {
              "match": {
                "price": "23"
              }
            }
          ]
        }
      }
    }``
    
    

    

  • 过滤查询
    gte：>=
    lte：<=

    GET mall/goods/_search
    {
      "query": {
        "bool": {
          "must": [
            {
              "match": {
                "b_name": "如何征服"
              }
            }
          ],
          "filter": {
            "range": {
              "price": {
                "gte": 10,
                "lte": 40
              }
            }
          }
        }
      }
    }
    

    

  • 快速模糊匹配查询(多个条件用空格隔开)，相当于 or

    GET mall/goods/_search
    {
      "query": {
        "match": {
          "b_name": "如何 骗"
        }
      },
      "_source": ["b_name"]
    }
