Solr LatLonType multivalued = true，以按多个点中最接近的点对文档进行排序

Question

The official Solr documentation were clear about this issue :

Fields using LatLonType must be single valued (ie multiValued="false")

The question is why there is such limitation, and how it's possible to extend Solr to support this feature. Any tips would be useful.

Problem Details : I have a solr core that contains multiple documents (ex: place) with multiple location for each. Solr does not yet support AFAIK storing multivalued LatLonType . I have to implement a solution for this, by creating a query function that maps the multiple lat/lng locations to the nearest one using a given center point parameter ie multivalued geodist function. But I need some tips for doing that, from any experienced solr/lucene.

Answer 1

You can take a look at: Is it possible to add multiple location for a single node and solr can show all location for a search? You can index multiple geolocation for a node, the problem is, when you search you will find just the first geolocation.
