Lucene advanced spatial search
Bounding Box Spatial Strategy
Prefix Tree Strategy.
This package is about SpatialPrefixTree and any supporting classes.
Spatial Query options useful for client side requests
Strategies that serialize the shape (non-indexed).
Spatial4j stuff that ideally belongs in Spatial4j (isn't related to Lucene).
Advanced spatial utilities.
Spatial strategy that uses two fields.
The spatial-extras module, new to Lucene 6.5, is the new home for the original
lucene spatial module.
The principle interface to this module is a
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
For some sample code showing how to use the API, see SpatialExample.java in the tests.
The spatial-extras module uses Spatial4j heavily. Spatial4j is an ASL licensed library with these capabilities:
Historical note: The new spatial-extras module was once known as
Lucene Spatial Playground (LSP) as an external project. In ~March 2012, LSP
split into the spatial 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
