格式化Solr日期刻面參數

Question

下面是查找時間刻面的Solr。

http://localhost:8983/solr/corearticle/select?indent=on&q=viewtime:*&facet=true&facet.field=viewtime&facet.date=viewtime&facet.date.start=NOW/DAY-30DAYS&facet.date.end=NOW/DAY+30DAYS&facet.date.gap=+1DAY

並且在下面的結果：

<lst name="facet_counts"> 
<lst name="facet_queries"/> 
<lst name="facet_fields"> 
<lst name="viewtime">

<lst name="facet_ranges"/> 
<lst name="facet_intervals"/>

</lst> 

但這回默認YYYY-MM-DDTHH：MM：SSZ格式。我需要按照yyyy-MM-dd格式進行分組。

它不能改變，因爲所使用的日期格式是dateTime的標準表示形式的限制形式，如此處所述Working with Dates
