Hi Chris,

In order to make it work you have to concatenate lat/lon before it reaches indexing. You can do that by using processor chain and adding ConcatFieldUpdateProcessorFactory.

Hello solr users!

I am trying to use geospatial to do some basic distance search in Solr4.10

At the moment, I got it working if I have just on set of coordinate
(latitude,longitude) per document.

However, I need to get it to work when I have an unknown numbers of set of
coordinates per document: the document should be returned if any of its
coordinates is within the distance threshold of a given coordinate.


Below is how it is working when I have just one set of coordinate per
document.

<fieldType name="location"  class="solr.LatLonType"
subFieldSuffix="_coordinate"/>
<fieldType name="tdouble" class="solr.TrieDoubleField" precisionStep="8"
omitNorms="true" positionIncrementGap="0"/>

<field name="lon_lat" type="location" indexed="true"  stored="false"
  multiValued="false" />
<copyField source="latitude" dest="lon_lat_0_coordinate" />
<copyField source="longitude" dest="lon_lat_1_coordinate" />


The reason why I am using the copyField is because the latitude and
longitude are provided in separate fields, not in the "lat,lon" format.
So far, all my attempts to use multivalued failed, and I would greatly
appreciate some help.

Thanks!

Chris
