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 Field Search和Spatial Search，两者都使用facet.query来生成这样的链接。         Q = ：＆安培;元数=经纬度＆安培; PT = 41.3，-73.8＆安培; facet.field = AllergenicIngredients＆安培; facet.field =食物类型＆安培; facet.query = CREATEDATE：2013-08-27T23：00 ：23Z至2013-09-10T23：00：23Z]＆amp; facet.query = CreateDate：[2013-08-28T23：00：23Z to 2013-09-11T23：00：23Z]＆amp; facet.query = {！ frange l = 0 u = 100} geodist（）“＆gt;＆amp; facet.query = {！frange l = 100.00 = 3000} geodist（）＆amp; wt = xml＆amp; facet = true＆amp; 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.
