Solr中具有不同间隙/步距的范围构面

问题描述

当前请求是

{
  "query": "*:*","facet": {
    "prices": {
      "type": "range","field": "price","start": 0,"end": 100,"gap": 20
    }
  }
}

我需要检索范围的计数

0 TO 5
5 TO 10
10 TO 20
20 TO 30
30 TO 40
40 TO 50
50 TO 100
100 TO ?(NO END)

如何检索这些范围的计数的请求？

解决方法

range parameters listing shows you the available parameters及其含义。要获得5作为差距，请使用"gap": 5。要获取超出您范围的条目，请包括"other": "after"：

  "type": "range","field": "price","start": 0,"end": 100,"gap": 5,"other": "after"

对于您的自定义范围，您需要include the ranges explicitly。您不能将other与range一起使用，但是有一些解决方法：

  "ranges": [
      {"range": "[0,5)"},{"range": "[5,10)"},{"range": "[10,20)"},{"range": "[20,30)"},{"range": "[30,40)"},{"range": "[40,50)"},{"range": "[50,100)"},{"range": "[100,*]"},]
