Question

我有以下网址：

http://webaddress:8994/solr/crossmedia/select?q=MEM_ED_NUMBER:136250%20AND%20CM_TYPE:WEB_MOBILE&rows=0&wt=json&indent=true&json.facet={Level1:{type:terms,field:ENTRY_DATE,limit:100,facet:{Level2:    {type:terms,field:NAME_URL,limit:100,facet:{sum:"sum(PAGE_IMPRESSIONS)",sum2:"sum(PAGE_IMPRESSIONS)"}}}}}

产生以下结果：

{
  "responseHeader":{
    "status":0,
    "QTime":0,
    "params":{
      "q":"MEM_ED_NUMBER:136250 AND CM_TYPE:WEB_MOBILE",
      "json.facet":"{Level1:{type:terms,field:ENTRY_DATE,limit:100,facet:{Level2:{type:terms,field:NAME_URL,limit:100,facet:{sum:\"sum(PAGE_IMPRESSIONS)\",sum2:\"sum(PAGE_IMPRESSIONS)\"}}}}}",
      "indent":"true",
      "rows":"0",
      "wt":"json"}},
  "response":{"numFound":32,"start":0,"docs":[]
  },

            "buckets":[{
                "val":"www.newarkadvocate.com",
                "count":2,

        {
          "val":"2015-03-01T00:00:01Z",
          "count":2,
          "Level2":{
            "buckets":[{
                "val":"www.newarkadvocate.com",
                "count":2,
                "sum":7737596.0,
                "sum2":7737596.0}]}},
        {
          "val":"2015-04-01T00:00:01Z",
          "count":2,
          "Level2":{
            "buckets":[{
                "val":"www.newarkadvocate.com",
                "count":2,
                "sum":8968393.0,

我想做的是在ENTRY_DATE DESCENDING订购，但我无法理解。

我试过了

http://webaddress:8994/solr/crossmedia/select?q=MEM_ED_NUMBER:136250%20AND%20CM_TYPE:WEB_MOBILE&sort=ENTRY_DATE%20desc&rows=0&wt=json&indent=true&json.facet={Level1:{type:terms,field:ENTRY_DATE,limit:100,facet:{Level2:{type:terms,field:NAME_URL,limit:100,facet:{sum:"sum(PAGE_IMPRESSIONS)",sum2:"sum(PAGE_IMPRESSIONS)"}}}}}

这给了我相同的结果集，没有订单更改。

我试过了

http://webaddress:8994/solr/crossmedia/select?q=MEM_ED_NUMBER:136250%20AND%20CM_TYPE:WEB_MOBILE&rows=0&wt=json&indent=true&json.facet={Level1:{type:terms,field:ENTRY_DATE,sort:"ENTRY_DATE%20desc",limit:100,facet:{Level2:{type:terms,field:NAME_URL,limit:100,facet:{sum:%22sum(PAGE_IMPRESSIONS)%22,sum2:%22sum(PAGE_IMPRESSIONS)%22}}}}}

这给了我一个错误。

有人可以帮忙吗？

谢谢，鲍勃

这是我的SOLR请求：

http://webdev:8994/solr/crossmedia/select?q=MEM_ED_NUMBER:136250%20AND%20CM_TYPE:WEB_MOBILE&rows=0&wt=json&indent=true&json.facet=%20{Level1:%20{sort:%20{ENTRY_DATE:%20desc},%20type:terms,%20field:ENTRY_DATE,%20limit:100,%20facet:{Level2:%20{type:terms,field:NAME_URL,limit:100,facet:%20{sum:%22sum(PAGE_IMPRESSIONS)%22,sum2:%22sum(PAGE_IMPRESSIONS)%22}}}}}

Answer 1

试试这个：

http://webaddress:8994/solr/crossmedia/select?q=MEM_ED_NUMBER:136250%20AND%20CM_TYPE:WEB_MOBILE&rows=0&wt=json&indent=true&json.facet=
 {Level1:
   {sort: {ENTRY_DATE: desc},
    type:terms,
    field:ENTRY_DATE,
    limit:100,
    facet:{Level2:
       {type:terms,field:NAME_URL,limit:100,facet:
      {sum:%22sum(PAGE_IMPRESSIONS)%22,sum2:%22sum(PAGE_IMPRESSIONS)%22}}}}}

Answer 2

以下是我最终使用的数据，以使其正常工作

http://webdev.auditedmedia.com:8994/solr/crossmedia/select?q=MEM_ED_NUMBER%3A136250+AND+CM_TYPE%3AWEB_MOBILE&rows=0&wt=json&indent=true&json.facet={%22Level1%22:{%22type%22:%22terms%22,%22field%22:%22ENTRY_DATE%22,%22limit%22:100,%22sort%22:{%22index%22:%22desc%22},%22facet%22:{%22Level2%22:{%22type%22:%22terms%22,%22field%22:%22NAME_URL%22,%22limit%22:100,%22facet%22:{%22sum%22:%22sum(PAGE_IMPRESSIONS)%22,%22sum2%22:%22sum(PAGE_IMPRESSIONS)%22}}}}}

排序是第1级的一部分，它使用的是Index而不是Entry_Date

如何使用SOLR URL对结果集进行排序？
