The "SolrAdaptersForLuceneSpatial4" page has been changed by DavidSmiley: http://wiki.apache.org/solr/SolrAdaptersForLuceneSpatial4?action=diff&rev1=22&rev2=23 Comment: Removed note about indexing non-point needing tests -- it has now been tested and bugs were fixed (v4.1). * Polygon, LineString and other new shapes. All shapes are supported as indexed shapes and query shapes. Shapes other than point, rectangle and circle are supported via JTS -- an otherwise optional dependency. See JTS caveats below for more information. * Multi-valued indexed fields. This is critical for storing the results of automatic place extraction from text using natural language processing techniques with a gazetteer (a variant of "geocoding"), since a variable number of locations will be found. - * Index non-point shapes as well as points. Non-point shapes are essentially pixelated (i.e. gridded) to a configured resolution per shape -- an approximation. By default that resolution is defined by a percentage of the overall shape size, and it applies to query shapes too. Note: If extremely high precision of shape edges needs to be retained for accurate indexing, then this solution probably won't scale too well at indexing time (big indexes, slow indexing). On the other hand, ''query'' shapes generally scale well to the maximum configured precision regardless of shape size. Note: indexing shapes with area sorely [[https://issues.apache.org/jira/browse/LUCENE-4419|needs testing]]. + * Index non-point shapes as well as points.

Oddly, Solr 3 spatial only supports the bounding box of a circle. * Multi-value distance sort / score boost. Note: this is a preliminary unoptimized implementation that uses a fair amount of RAM, even when multiValued=false. An alternative should be provided in the future. * Configurable precision which can vary per shape at query time (and sort of at index time). This enhances the performance.
