How to return distance and score in spatial search

I'm writing a Spring MVC based Search API using spring-data-solr 1.0.0.RELEASE with Solr 4.4.0 and Spring 3.2.4.RELEASE.

I'm able to run basic queries but unable to find any good example how can I return score and distance:geodist() in the results.

I know I can get results from Solr using query like

http://localhost:8983/solr/events/select?q=*:*&spatial=true&pt=51.435872%2C-0.427529&sfield=position&d=20&facet=true&facet.mincount=1&facet.limit=-1&facet.field=categoryIds&fl=score,*,distance:geodist()&sort=geodist()+asc

but I don't know how to get score and distance properties returned from Solr using spring-data-solr. I have tried following code

FacetQuery search = new SimpleFacetQuery();

Criteria conditions;// = new Criteria();
if(StringUtils.isNotBlank(searchCriteria.getSearchString()))
        conditions = new Criteria(EventDocument.FIELD_EVENT).contains(searchCriteria.getSearchString());

if(searchCriteria.isLocationKnown()){
        conditions.and(new Criteria(EventDocument.FIELD_POSITION).within(new GeoLocation(searchCriteria.getLatitude(), searchCriteria.getLongitude()), new Distance(searchCriteria.getDistance(), Distance.Unit.MILES)));
        conditions.and(new Criteria(CommonParams.FL).is("score,distance:geodist(),*"));
    } else{
        conditions.and(new Criteria(CommonParams.FL).is("score,*"));
    }

search.addCriteria(conditions);
FacetPage page = solrTemplate.queryForFacetPage(search, EventDocument.class);

but getting following Exception:

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.springframework.data.solr.UncategorizedSolrException: undefined field fl; nested exception is org.apache.solr.client.solrj.impl.HttpSolrServer$RemoteSolrException: undefined field fl

Thanks for any attention and help!!!

To set fl you have to use query.addProjectionOnField(String fieldname).

    SimpleQuery query = new SimpleQuery(conditions);
    query.addProjectionOnField("*");
    query.addProjectionOnField("score");

For mapping score into EventDocument you'll have to add the property as follows.

    @Indexed(value = "score", readonly = true)
    private Float score;

Unfortunately there seems to be an issue with geodist() that might be caused by the way spring data solr creates spatial query. Opended DATASOLR-130 for that.

Distance can be requested using SolrCallback along with SolrTemplate by setting spatial paramters yourself.

    SimpleQuery query = new SimpleQuery(conditions);
    query.addProjectionOnField("*");
    query.addProjectionOnField("distance:geodist()");

    DefaultQueryParser qp = new DefaultQueryParser();
    final SolrQuery solrQuery = qp.constructSolrQuery(query);
    solrQuery.add("sfield", "store");
    solrQuery.add("pt", GeoConverters.GeoLocationToStringConverter.INSTANCE.convert(new GeoLocation(45.15, -93.85)));
    solrQuery.add("d", GeoConverters.DistanceToStringConverter.INSTANCE.convert(new Distance(5)));

    List<EventDocument> result = template.execute(new SolrCallback<List<EventDocument>>() {

      @Override
      public List<EventDocument> doInSolr(SolrServer solrServer) throws SolrServerException, IOException {
        return template.getConverter().read(solrServer.query(solrQuery).getResults(), EventDocument.class);
      }
    });

A litte bit easier would be to provide required parameters for geodist().

    SimpleQuery query = new SimpleQuery(conditions);
    query.addProjectionOnField("*");
    query.addProjectionOnField("distance:geodist(store," + GeoConverters.GeoLocationToStringConverter.INSTANCE.convert(new GeoLocation(45.15, -93.85)) + ")");
    Page<EventDocument> result = template.queryForPage(query, EventDocument.class);

hope that helps!
