pseudofield to return distance

   . [[http://localhost:8983/solr/select?wt=json&indent=true&fl=name,store&q=*:*&fq={!geofilt}&sfield=store&pt=45.15,-93.85&d=50&sort=geodist()%20asc|...&q=*:*&fq={!geofilt}&sfield=store&pt=45.15,-93.85&d=50&sort=geodist()

  == Returning the distance ==
- Returning distances (and any arbitrary function query value) is currently under development.
As a temporary workaround, it's possible to obtain distances by using geodist or geofilt as
the only scoring part of the main query.
+ <!> [[Solr4.0]]
+ 
+ You can use the pseudo-field feature to return the distance along with the stored fields
of each document by adding '''fl=geodist()''' to the request.  Use an alias like '''fl=_dist_:geodist()'''
to make the distance come back in the '''_dist_''' pseudo-field instead.  Here is an example
of sorting by distance ascending and returning the distance for each document in '''_dist_'''.
