如何优化Oak Lucene索引以减少索引时间

Last update: Tue Jul 16 2024 00:00:00 GMT+0000 (Coordinated Universal Time)

使用includedPaths和excludedPaths属性优化Oak Lucene索引。

描述 description

环境

Adobe Experience Manager 6.0 + Oak 1.0.16或更高版本
Adobe Experience Manager 6.1和6.2

问题/症状

优化AEM Oak Lucene索引以减少重新索引时间。

解决方法 resolution

您可以通过微调Oak： QueryIndexDefinition的includedPaths、excludedPaths、name和indexPath等属性来优化Oak Lucene索引。

includedPaths和excludedPaths属性限制索引在重新索引时遍历的路径以及它侦听索引更新的路径。
name和indexPath属性使索引日志更容易理解，因为它们会使用索引的路径或名称标记日志消息。例如：

30.01.2017 14:07:12.934 *DEBUG* [ pool-8-thread-2] org.apache.jackrabbit.oak.plugins.index.lucene.LuceneIndexEditor [ damassetlucene(

/oak :index /damAssetLucene )] => Indexed 9000 nodes...

优化索引的步骤：

前往 http://aem-host:port/crx/de/index.jsp 并以管理员身份登录。
浏览到/oak:index。
将[ 1]下方高亮显示的属性添加到相应的索引。 includedPaths 和 excludedPaths 属性应为multi-value String (String[ ] )。
在CRXDe中单击 全部保存。
