如何使用 SOLR url 对结果集进行排序？
How do I sort result set using a SOLR url?
我有以下 URL:
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：

我想做的是按 ENTRY_DATE 降序排列，但我没弄对。
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，没有顺序变化。
