We have a custom Lucene index configured on our Content Management and Content Delivery server. The rebuild strategies on the index are
<strategy ref="contentSearch/indexConfigurations/indexUpdateStrategies/onPublishEndAsync" />
<strategy ref="contentSearch/indexConfigurations/indexUpdateStrategies/remoteRebuild" />
The issue is that the Lucene index on the Content Management server is not in sync with the index on the Content Delivery server. The only way to keep them in sync is to manually trigger an index rebuild on the Content Management server.
Is this expected behavior or is there a misconfiguration somewhere?
