In an experiment, I want to build the site specific index in the CD environment manually right after publish event. I created a processor which is hooked in the publish end event for rebuilding the index. This is now rebuilding of the entire sites index in a Sitecore instance.
This is time consuming in the publishing process. But what I want to achieve is that rebuild only the index specific to the items that are getting published from different sites like
onpublishendasync update strategy, I assume this is how it does it. This means only the delta update not all the index. How do I achieve with manual strategy? Any suggestion would really be helpful.
