A Metadata Index is included with your Titan instance. There is no additional build needed to be run for the Metadata Index. When using Metadata Index, the Search Results block on display side will search your content's properties' Page Title, Metatag Keyword and Description. In order to search content, configure the dtSearch Index instead of the Metadata Index. Any time content is added or changed the dtSearch Index job will pick up changes at the schedule run time or you may manually kick off the job sooner.
