Subject [Solr Wiki] Update of "SpatialSearch" by GrantIngersoll
Date Tue, 13 Apr 2010 13:31:27 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=15&rev2=16

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

  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 the Spatial Filter QParser (!SpatialQParser)  - See https://issues.apache.org/jira/browse/SOLR-1568
- as in {!sfilt fl=location}&pt=49.32,-79.0&dist=20
+  1. By the Spatial Filter QParser (!SpatialQParser)  - e.g. {!sfilt fl=location}&pt=49.32,-79.0&d=20
   1. Using the "frange" QParser, as in {{{fq={!frange l=0 u=400}hsin(0.57, -1.3, lat_rad,
lon_rad, 3963.205)}}}
  
  In practice, for those using Solr's field types above, the Spatial Filter !QParser will
automatically make the correct decision about how best to filter.  If an application needs
a specific type of filtering for performance or other needs, the best bet is to extend the
!FieldType in question with your own needs.

  https://issues.apache.org/jira/browse/SOLR-1297 added the ability to sort by function, so
sorting by distance is now simply a matter of sorting using the appropriate distance function,
just like boosting.
