elasticsearch过滤器聚合不起作用

Question

就像this 帖子一样，我无法让过滤器 agg 工作：

GET files/_search
{
  "query": {
    "match": {
      "words": "sugar"
    }
  },
  "aggs": {
    "xxx": {
      "filters": {
        "filter_list": {
          "errors": {
            "term": {
              "abstract": "error"
            }
          },
          "warnings": {
            "term": {
              "abstract": "warning"
            }
          }
        }
      },
      "aggs": {
        "st": {
          "significant_terms": {
            "field": "abstract"
          }
        }
      }
    }
  }
}

SearchParseException[[files][3]: query[words:sugar],from[-1],size[-1]: 解析失败 [[xxx] 中 START_OBJECT 的未知键： [过滤器列表]。]]; }{[tIS8uY8nTDil6kWtgsbkQg][文件][4]： SearchParseException[[files][4]: 查询[words:sugar],from[-1],size[-1]: 解析失败 [解析源失败 [{\n \"query\": {\n

您只有一件事错了，即filter_list 应改为filters，因为它是filters aggregation 的强制元素。

GET files/_search
{
  "query": {
    "match": {
      "words": "sugar"
    }
  },
  "aggs": {
    "xxx": {
      "filters": {
        "filters": {           <---- change this
          "errors": {
            "term": {
              "abstract": "error"
            }
          },
          "warnings": {
            "term": {
              "abstract": "warning"
            }
          }
        }
      },
      "aggs": {
        "st": {
          "significant_terms": {
            "field": "abstract"
          }
        }
      }
    }
  }
}
