替代IndexProvider for Neo4J 1.9.1

Question

我在我的应用程序中使用Lucene 4并且不想更改它.我正在尝试集成Neo4J,它将Lucene 3.5捆绑为IndexProvider实现,neo4j-lucene-index.

不幸的是,neo4j-lucene-index不起作用,并且排除了这种依赖性,应用程序只会在启动时无限期挂起.我已经尝试过neo4j-lucene4-index,但这似乎没有得到很好的维护,需要更新才能与Neo4J 1.9.1一起使用.这些变化超出了我对Neo4J内部的理解.

但是,我可以看到IndexProviders是可插拔的,所以我希望有一个现有的Lucene替代品 - 我现在无法找到它.任何人都可以指出我正确的方向吗？

Lucene 4已经出现了很长时间并且Neo4J不支持它,这似乎很奇怪.我错过了什么吗？

目前,我的POM对于我的Neo4J配置看起来像这样:

从 1.8 -> 1.9 内部发生了一些变化。简而言之，索引提供者必须通过 META-INF/services 注册 KernelExtensionFactory，请参阅https://github.com/neo4j/neo4j/blob/master/community/lucene-index/src/main/resources/META-INF/服务/org.neo4j.kernel.extension.KernelExtensionFactory

这个 KernelExtensionFactory 是入口点，只需在https://github.com/neo4j/neo4j/tree/master/community/lucene-index上查看基于 Lucene 3 的实现即可。
