在提交数据时的格式为：（纬度,经度：以字符串的方式提交给solr）

<field name="store">45.17614,-93.87341</field>  <!-- Buffalo store -->
<field name="store">40.7143,-74.006</field>     <!-- NYC store -->
<field name="store">37.7752,-122.4232</field>   <!-- San Francisco store -->

例如要查寻距离纬度经度（31.254982,121.47501）5km的所有满足条件的楼盘：
http://192.168.181.140:8487/solr/loupan/select/?q=city_id:11&fq={!geofilt pt=31.254982,121.47501 sfield=latlng d=5}
查找满足指定距离的结果集，并按照距离由近到远排序
http://192.168.181.140:8487/solr/loupan/select/?q=*:*&fq={!geofilt}&pt=31.2367,121.501&sfield=latlng&d=5&sort=geodist()+asc
