Extend alfresco subsystem

Alfresco Repository subsystem and its extension paths
or
How to extend alfresco sub-system?

If you're extending alfresco repository make sure you've used proper extension paths. Otherwise, your customization will not be loaded into Alfresco.

Last week, we were trying to extend to SOLR, Lucene searches,when I use the following paths it was not working.

classpath*:alfresco/extension/subsystems/Search/noindex/*-context.xml
classpath*:alfresco/extension/subsystems/Search/solr/*-context.xml
classpath*:alfresco/extension/subsystems/Search/lucene/*-context.xml

I faced NoSuchBean exception. Then I debugged the spring and alfresco bootstrap code then found the following path for alfresco extensions.
Later i found i need to one level down to extend the search subsystem.
