solrnet - 如何使用多个 Solrnet facet.query 参数将 facet_counts 结果分组到单独的类别中？

Question

我已经实现了 CreateDate 字段搜索以及空间搜索，两者都使用 facet.query 来生成这样的链接。q= : &sfield=latlng&pt=41.3,-73.8&facet.field=AllergenicIngredients&facet.field=FoodType&facet.query=创建日期：[2013-08-27T23:00:23Z TO 2013-09-10T23:00:23Z]&facet.query=创建日期：[2013-08-28T23:00:23Z TO 2013-09-11T23:00:23Z]&facet.query={!frange l=0 u=100}geodist()">&facet.query={!frange l =100.00=3000}geodist()&wt=xml&facet=true&fl=*, dist :geodist().

The facet_counts element of the response XML looks like this.

<lst name="facet_counts">
    *<lst name="facet_queries">
        <int name="CreateDate:[2013-08-27T23:00:23Z TO 2013-09-10T23:00:23Z]">7</int>
        <int name="CreateDate:[2013-08-28T23:00:23Z TO 2013-09-11T23:00:23Z]">4</int>
        <int name="{!frange l=0 u=100}geodist()">2</int>
        <int name="{!frange l=100.001 u=3000}geodist()">6</int>
    </lst>*
    <lst name="facet_fields">
      <lst name="AllergenicIngredients">
        <int name="Not Allergenic">6</int>
        <int name="Nuts">2</int>
      </lst>
      <lst name="FoodType">
        <int name="Non-Vegetarian">6</int>
        <int name="Vegetarian">2</int>
      </lst>
    </lst>
    <lst name="facet_dates"/>
    <lst name="facet_ranges"/>
</lst>


I am able to group the facet_fields count results by their names(AllergenicIngredients,FoodType) but how do I group the facet_queries (*italicized*) count by CreatDate and Distance. My website is .Net based and is using Solrnet.
