Make a framework for users to be able to inject their own meta words and create their own subdocuments of documents associated with metas words. Give a hook so that after a crawl is completed a post processing function is called. In the post processing call a plugin can retrieve injected meta words, do post processing on them such as clustering, calculate page rank, etc, and then inject new words and documents back into the index.

Additional information: This was supported with the creation of the recipe plugin
