The format for data submission is: (latitude, longitude: Submitted to SOLR in string Mode)

<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 -->

For example, to search for all buildings that meet the conditions 31.254982 from the latitude longitude (121.47501, 5km:

 

Http: // 192.168.181.140: 8487/SOLR/loupan/select /? Q = city_id: 11 & FQ = {! Geofilt Pt = 31.254982, 121.47501 sfield = latlng d = 5}

Find the result set that meets the specified distance and sort the result set by distance from near to far

Http: // 192.168.181.140: 8487/SOLR/loupan/select /? Q = *: * & FQ = {! Geofilt} & Pt = 31.2367, 121.501 & sfield = latlng & D = 5 & sort = geodist () + ASC
