The spatial module is new to Lucene 4, replacing the old "contrib" module
that came before it. The principle interface to the module is
a SpatialStrategy
which encapsulates an approach to indexing and searching
based on shapes. Different Strategies have different features and
performance profiles, which are documented at each Strategy implementation
class level.
For some sample code showing how to use the API, see SpatialExample.java in the tests.
The spatial module uses Spatial4j heavily. Spatial4j is an ASL licensed library with these capabilities:
Historical note: The new spatial module was once known as
Lucene Spatial Playground (LSP) as an external project. In ~March 2012, LSP
split into this new module as part of Lucene and Spatial4j externally. A
large chunk of the LSP implementation originated as SOLR-2155 which uses
trie/prefix-tree algorithms with a geohash encoding. That approach is
implemented in RecursivePrefixTreeStrategy
today.
