在 elasticsearch 中对嵌套术语执行文本搜索和过滤

Question

我正在尝试执行搜索，例如在描述中搜索郊狼一词，但它们是红色和绿色，并且属于卡通类别。现在我想我明白你不能在同一个查询中有匹配和术语（下面的查询因为这个原因不起作用），而且你也知道你不应该使用术语来搜索文本字段。谁能指出我正确的方向？

这是我的查询

GET /searchproducts/_search
{
    "query": {
      "match": {
      "description": {
        "query": "coyote"
      }
    },
        "bool": {
            "should": [{
                    "terms": {
                        "colours.name": ["red", "green"]
                    }
                },
                {
                    "terms": {
                        "categories.name": ["Cartoon"]
                    }
                }
            ]
        }
    },
    "aggs": {
        "colours": {
            "terms": {
                "field": "colour.name.value",
                "size": 100
            }
        },
        "categories": {
            "terms": {
                "field": "categories.id",
                "size": 100
            }
        }
    }
}

您可以使用 bool query 组合多个查询。试试这个查询：

{
  "query": {
    "bool": {
      "should": [
        {
          "match": {
            "description": {
              "query": "coyote"
            }
          }
        },
        {
          "bool": {
            "should": [
              {
                "terms": {
                  "colours.name": [
                    "red",
                    "green"
                  ]
                }
              },
              {
                "terms": {
                  "categories.name": [
                    "Cartoon"
                  ]
                }
              }
            ]
          }
        }
      ]
    }
  },
  "aggs": {
    "colours": {
      "terms": {
        "field": "colour.name.value",
        "size": 100
      }
    },
    "categories": {
      "terms": {
        "field": "categories.id",
        "size": 100
      }
    }
  }
}
