The neo4j being used is the current latest version: 3.1.0, various tread pits. Say how to use the Chinese index in neo4j 3.1.0. Choose the Ikanalyzer to do the word breaker. 1. First refer to the article: https://segmentfault.com/a/1190000005665612 The way of indexing with Ikanalyzer is roughly spoken. But it is not clear, in fact, the background of this article is to use embedded

https://www.ibm.com/developerworks/cn/java/j-lo-neo4j/NEO4J is a high-performance NoSQL graphics database. NEO4J uses graph-related concepts to describe data models, saving data as nodes in diagrams and relationships between nodes. The relationship between data in many applications can be modeled directly using the concept of nodes and relationships in the diagra

neo4j Introduction Graph database Requirements  can be clearly intuitive way to store the graph data, rather than distort the change for other alternative way  can simply map operations, such as search, traversal, etc. The basic idea of the graph database (graph) is composed of nodes (node, vertex) and relation (relationship, edge) to record data on nodes (properties of nodes, property)  nodes are organized into graphs by the relationship, and the

in the message load and execute these queries, and return results in the HTTP response. It is precisely this restful API interface that allows existing Neo4j drivers to be created. Py2neo provides simple encapsulation of these REST resources, so that Python application developers can use Neo4j with confidence without considering the underlying client-server protocol. A simple application To verify py2neo,

Py2neo provides a simple encapsulation of these rest resources, which allows Python application developers to be comfortable with neo4j without having to consider the underlying client-server protocol. A simple applicatio

Create a Neo4j Cluster Environment Introduction: Neo4j is currently the mainstream graph database. It also provides highly available cluster solutions. This article will try to build a highly available Neo4j environment. 1. What is graph database? Graphic database is a set of data stored in the same row as certain data on the basic elements of vertices, wires, an

Currently, the neo4j documentation is limited to official documents. This article will sort out the main official documents of neo4j for reference and the content will be updated continuously! Start Features Acid transactions High Availability Scalable to hundreds of millions of nodes and relationships High-speed Traversal Deployment mode Single Instance Mult

Last Review: This article mainly describes the Neo4j Spatial project and space data (vector) storage. This article describes how to integrate Neo4j Spatial with Neo4j Server and GeoServer. Noted: it is feasible to integrate with Geoserver, but geoserver cannot display the layers in the Publishing Database. (System environment: Ubuntu 12.04, Spatial 0.9,

1. Introduction to Neo4j Neo4j is a high-performance, NoSQL graph database implemented in Java. Neo4j uses graph-related concepts to describe the data model, and uses the relationship between nodes in the graph to model. Neo4j is fully compatible with ACID transactions. Neo4j
