Subject [Solr Wiki] Update of "SpatialSearch" by GrantIngersoll
Date Tue, 16 Mar 2010 13:21:02 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Solr Wiki" for change notification.

The "SpatialSearch" page has been changed by GrantIngersoll.
http://wiki.apache.org/solr/SpatialSearch?action=diff&rev1=12&rev2=13

--------------------------------------------------

  Then, to query, the system can use the distance Functions in Solr, as in:
  
  {{{
- http://localhost:8983/solr/select/?q=_val_:"recip(dist(2, store, point(34.0232,-81.0664)),1,1,0)"&fl=*,score
+ http://localhost:8983/solr/select/?q=_val_:"recip(dist(2, store, vector(34.0232,-81.0664)),1,1,0)"&fl=*,score
  }}}
  The above computes the [[http://wiki.apache.org/solr/FunctionQuery#dist|the Euclidean distance]]
from the point (34.0232,-81.0664) to the store's point, asking SOLR to [[http://wiki.apache.org/solr/FunctionQuery#recip|invert
the distance]] (take 1 / the distance) in order to make longer distances come later in the
result list, and finally asking SOLR to return all fields, including the relevancy score.
