推荐答案

您必须安装 Apoc 程序插件 (https://github.com/neo4j-contrib/neo4j-apoc-procedures).关于 ES 集成的文档在这里:ES 与 Apoc 程序的集成

You have to install Apoc procedures plugin (https://github.com/neo4j-contrib/neo4j-apoc-procedures). The documentation about ES integration is here : ES Integration with Apoc procedures

• 将 apoc.jar 下载并放到插件的 Neo4j 目录中，关于目标 Neo4j 版本

• download and drop apoc.jar in plugins's Neo4j directory, regarding the targetted Neo4j version

重启 Neo4j

在 Neo4j Web 浏览器中，启动以下 Cypher 查询以显示所有 ES 过程:

in Neo4j Web browser, launch the following Cypher query to show all ES procedures:

CALL apoc.help("apoc.es")

日志示例查询:

CALL apoc.es.getRaw("localhost","_search?q=level:ERROR",null) 
YIELD value 
UNWIND value.hits.hits as hits
RETURN hits LIMIT 100

推荐的方式是在neo4j.conf中添加一个key(Neo4j重启后)存放ES主机:

The recommanded way is to store the ES host in neo4j.conf by adding a key (after restart of Neo4j):

apoc.es.myKey.url=localhost

然后查询看起来像:

CALL apoc.es.getRaw("myKey","_search?q=level:ERROR",null) 
YIELD value 
UNWIND value.hits.hits as hits
RETURN hits LIMIT 100
