Subject [Solr Wiki] Update of "SpatialSearch" by GrantIngersoll
Date Mon, 28 Dec 2009 23:29:41 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=9&rev2=10

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

  See https://issues.apache.org/jira/browse/SOLR-1586 for the !SpatialTileField, which can
index points into tiles at multiple levels.
  
  = Indexing =
+ 
+ Indexing is handled by the various !FieldType instances in the schema.  At the most basic,
the user can represent their own spatial data using ints, floats or doubles.  Beyond that,
the !PointType, !GeoHashField and !SpatialTileField can be used to index spatial information
automatically.
+ 
  = Filtering =
  There are several different ways to filter in spatial search:
  
   1. By Range Query, as in {{{fq=lat:[-23.0 TO -79.5] AND lon:[56.3 TO 60.3]}}} -- Already
implemented
-  1. By Cartesian Tier - See https://issues.apache.org/jira/browse/SOLR-1568 - <!>
TODO <!> - fill in details
+  1. By the Spatial Filter QParser  - See https://issues.apache.org/jira/browse/SOLR-1568
- <!> TODO <!> - fill in details, including the name of the QParser.
   1. Using the "frange" QParser, as in {{{fq={!frange l=0 u=400}hsin(0.57, -1.3, lat_rad,
lon_rad, 3963.205)}}}
