Hi Sir,
*Scenario*:
I have to return the distances for every city search so I make these
configurations as described below.
*solrconfig.xml: *
My request handler is "im.search" and its defaults are
<lst name="defaults">
<str name="echoParams">none</str>
<str name="wt">json</str>
<str name="rows">20</str>
<str name="lat">0</str>
<str name="lon">0</str>
</lst>
<str name="fl">title,city,state,distance:geodist($lat,$lon,latlon)</str>
*schema.xml: *
<fieldType name="latlongtype" class="solr.LatLonType"
subFieldSuffix="_coordinate"/>
<field name="latlon" type="latlongtype" indexed="true" stored="true"
required="false" multiValued="false" />
*query 1: *
*http://localhost:8020/solr/search1/select/?q=bags&qt=im.search&ps=1&group.limit=1&spellcheck=true&lat=23.26667&lon=77.4&boost=recip(geodist(23.26667,77.4,latlon),13.97,12000,5000)&facet.query=city
<http://localhost:8020/solr/search1/select/?q=bags&qt=im.search&ps=1&group.limit=1&spellcheck=true&lat=23.26667&lon=77.4&boost=recip(geodist(23.26667,77.4,latlon),13.97,12000,5000)&facet.query=city>:"bhopal"*
*Results:*
{
"title":"Colored Gift Bags",
"city":"Indore",
"state":"Madhya Pradesh",
"distance":171.58415508651908},
{
"title":"Paper Carry Bags",
"city":"Indore",
"state":"Madhya Pradesh",
"distance":171.58415508651908},
{
"title":"Handmade Paper Bags",
"city":"Indore",
"state":"Madhya Pradesh",
"distance":171.58415508651908},
{
"title":"Bulk Bags",
"city":"Indore",
"state":"Madhya Pradesh",
"distance":171.58415508651908},
{
"title":"Filter Bags",
"city":"Indore",
"state":"Madhya Pradesh",
"distance":171.58415508651908},
{
"title":"HDPE Woven Bags",
"city":"Indore",
"state":"Madhya Pradesh",
"distance":171.58415508651908
}
which is fine for all the distance calculation
*query 2:*
*http://localhost:8020/solr/search1/select/?q=bags&qt=im.search&ps=1&group.limit=1&spellcheck=true
<http://localhost:8020/solr/search1/select/?q=bags&qt=im.search&ps=1&group.limit=1&spellcheck=true>*
*Results:*
{
"title":"PVC Transparent Bags",
"city":"Ghaziabad",
"state":"Uttar Pradesh",
"distance":8783.780020683036},
{
"title":"Sand Bags",
"city":"Bharuch",
"state":"Gujarat",
"distance":8251.412123848868},
{
"title":"Carry Bags",
"city":"Mumbai",
"state":"Maharashtra",
"distance":8211.624964681945},
{
"title":"Shoulder Bags",
"city":"Mumbai",
"state":"Maharashtra",
"distance":8211.624964681945},
{
"title":"Valve Type Bags",
"city":"Bharuch",
"state":"Gujarat",
"distance":8251.412123848868},
{
"title":"Laptop Bags",
"city":"Delhi",
"state":"Delhi",
"distance":8762.7634687622},
{
"title":"Jute Bags",
"city":"Ghaziabad",
"state":"Uttar Pradesh",
"distance":8783.780020683036
}
But in this case i am getting the variable distance which is not
understandable that how and using which area coordinate, it is calculating
the distance, because i think it must be some constant in this case.
