如何在Apache solr上進行facet組查詢

Question

我正在對solr進行一個方面的查詢..這給了我各個方面的方面和計數......但是現在我想在方面上執行一個組查詢..這讓我按照組計數...

例

以下是數據

第1項：耐克鞋（尺碼：8,9,10）第2項：Reebok鞋（尺碼：8,9,10）

現在在這種情況下我的品牌facet查詢返回結果如下

• 耐克：3

• 銳步：3

我需要的結果是

• 耐克：1
• 銳步：1

問候

Answer 1

是否啟用group.facet =真正的解釋在這里 。 你需要至少3.3

Answer 2

http://1XX.XXX.XXX.XXX:8080/solr/autocomplete/select?q=displayterm:new&wt=json&indent=true&q.op=and&fl=displayterm&group=true&group.field=displayterm

注意： ＆group = true＆group.field = displayterm
該響應通過displayterm成為組
