Which new documents should be added only to a conceptual index data source before running an incremental build?

In the context of managing a conceptual index data source, the ideal choice involves adding documents that do not introduce new concepts. This approach ensures that the incremental build remains focused on enriching the existing framework of concepts already present without overwhelming it with irrelevant information.

By adding documents with no new concepts, you are effectively reinforcing or updating the existing knowledge base without creating potential noise or redundancy in the index. This maintains the clarity and efficiency of the indexing process, allowing the incremental build to operate smoothly and retain its conceptual integrity.

Adding documents that introduce new concepts might unnecessarily complicate the index, while including documents representing a minor fraction of the overall population could detract from the priority of processing more significant updates. As for the option of including all documents, this would likely be counterproductive, as it would dilute the focus from the essential updates needed to improve the quality and relevance of the index.
