#neo4j_trie_plugin The original Neo4j Spatial plugin for Neo4j Graph database uses RTree for geometry calculation, which is not scalable for hanlding large number of Nodes for frequent time consuming splitting and joining operations.

Geohash on the other hand, suit the need of neighborhood calculation and is implemented in databases like mongoDB, but unfortunately not in Neo4j.

This project implement Geohash algorithm based on Neo4j graph database, with a specially designed trie tree structure for fast and efficient retrieval. The Geohash implementation is borrowed from geohash-java and the project is licensed under LGPL license. For commercial usage, contact Dong bin at Linkedin, China(dongbin.cn at gmail.com).

First install and configure neo4j.

For Mac users: Execute "brew install neo4j" in terminal. Then find /usr/local/Cellar/neo4j/x.x.x/libexec/conf/neo4j-server.properties,

change dbms.security.auth_enabled from true to false to disable authentication.

Execute "mvn compile" to build.

For PrefixTree Test, run PrefixTreeTest for individual functionality test and TestAll for high level experience.

For Plugin Test, run SpatialPluginFunctionTest.
