Elasticsearch 內聯腳本過濾器不起作用

Question

我正在嘗試在 ES-2.3.4 上執行以下查詢。 如果您在最后刪除內聯腳本，查詢將按預期工作。 但是如果我包含腳本，查詢應該返回結果，但它沒有。 這是一個很棒的腳本。 其中“bio”是嵌套對象。 任何人都可以驗證查詢並建議我是否需要進行任何更改。

    "must" : [ {
      "nested" : {
        "query" : {
          "term" : {
            "bio.cl" : "Position"
          }
        },
        "path" : "bio"

    }, {

              }
            }
          }

Answer 1

跟進我們在上述評論中的討論......

您需要正確連接數組，即

[stop] + _source.biomarkers.collect{it.stop}

將使用[stop, bio[0].stop, bio[1].stop, etc]創建一個數組，然后我們可以獲取該數組的max() 。

所以我建議這樣的事情應該有效（雖然未經測試）

percent <= (([stop] + _source.biomarkers.collect{it.stop}).min() - ([start] + _source.biomarkers.collect{it.start}).max()) / ([length] +_source.biomarkers.collect{it.stop - it.start + 1}).max()
