如何使用SOLR URL對結果集進行排序？

我有以下網址：如何使用SOLR URL對結果集進行排序？

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)"}}}}}

產生以下結果：

{ 
    "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":[] 
    }, 
    "facets":{ 
    "count":32, 
    "Level1":{ 
     "buckets":[{ 
      "val":"2015-01-01T00:00:01Z", 
      "count":2, 
      "Level2":{ 
      "buckets":[{ 
       "val":"www.newarkadvocate.com", 
       "count":2, 
       "sum":7118768.0, 
       "sum2":7118768.0}]}}, 
     { 
      "val":"2015-02-01T00:00:01Z", 
      "count":2, 
      "Level2":{ 
      "buckets":[{ 
       "val":"www.newarkadvocate.com", 
       "count":2, 
       "sum":7458540.0, 
       "sum2":7458540.0}]}}, 
     { 
      "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,

我想這樣做是爲了它ENTRY_DATE DESCENDING，但我不能讓它正確的。

我已經試過

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)"}}}}}

這給了我同樣的結果集，沒有順序的變化。

我已經試過

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}}}}}

這給了我一個錯誤。

有人可以幫忙嗎？

感謝，鮑勃

這裏是我的SOLR要求：

試試這個：

http://webaddress:8994/solr/crossmedia/select?q=MEM_ED_NUMBER:136250%20AND%20CM_TYPE:WEB_MOBILE&rows=0&wt=json&indent=true&json.facet=

    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}}}}}

我複製了你的上面的URL，把webaddress改成了實際的地址並運行它，並得到了下面的錯誤信息。看下一個答案。 –

修正了排序必須執行的級別，現在試試吧？ – Persimmonium

這次有不同的錯誤。它張貼在下面。感謝您花時間幫助我解決這個問題。 –

這裏是我最後使用了我的數據，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}}}}}

此排序是第1級的一部分，它是我們ing索引而不是Entry_Date
