[[Solr4.0]], start the example server and index the example data as shown in

Solr server running, you should be able to click on the example links and see

  In the example data, certain documents have a field called "store" (with a 
fieldType named "location" implemented via !LatLonType).  Some of the points in

  === Filtering Caveats ===
  For the {{{bbox}}} filter, when the bounding box includes a pole, the 
!LatLonType will switch from producing a bounding box to a "bounding bowl" 
(i.e. a [[http://mathworld.wolfram.com/SphericalCap.html|spherical cap]]) 
whereby it will include all values that are North or South of the latitude of 
the would be bounding box (the lower left and the upper  right) that is closer 
to the equator.  In other words, we still calculate what the coordinates of the 
upper right corner and the lower  left corner of the box would be just as in 
all other filtering cases,  but we then take the corner that is closest to the 
equator (since it  goes over the pole it may not be the lower left, despite the 
name) and  do a latitude only filter.  Obviously, this means there will be more 
 matches than a pure bounding box match, but the query is much easier to  
construct and will likely be faster, too.
  
+ = New Solr 4 Spatial Field Types =
+ Lucene 4 has a new spatial module that replaces the older one before it.  The 
Solr adapters for it are documented here: SolrAdaptersForLuceneSpatial4

  SpatialSearchDev -- Covers things like Geohash (supports multivalue lat-lon 
points), other distance functions, etc.
