Sorting by distance fails when using result grouping
----------------------------------------------------

                 Key: SOLR-2642
                 URL: https://issues.apache.org/jira/browse/SOLR-2642
             Project: Solr
          Issue Type: Bug
          Components: search
    Affects Versions: 3.3
            Reporter: Thomas Heigl


When using result grouping, sorting by distance with geodist() fails because of missing weights
for sorts.

A an example of a failing query on an index with standard schema.xml looks like this:

{code}
q=*:*&group=true&group.field=user.uniqueId_s&group.main=true&group.format=grouped&sfield=user.location_p&pt=48.20927,16.3728&sort=geodist()
asc
{code}

The exception thrown is:

{code}
Caused by: org.apache.solr.common.SolrException: Unweighted use of sort geodist(latlon(user.location_p),48.20927,16.3728)
