Hi, I just released this plugin > **[jprante/elasticsearch-analysis-reference](https://github.com/jprante/elasticsearch-analysis-reference)** > > elasticsearch-analysis-reference - A reference mechanism for including content from other documents during the Elasticsearch analysis field mapping phase It uses a reference mechanism for including content from other documents in the cluster during the analysis field mapping phase. This process is also known as denormalization. Denormalization can be defined as the copying of the same data into multiple documents in order to simplify query processing or to fit the user’s data into a particular data model. See the example at the github page how to create a library catalog entry for the book "Goethe's Faust" and making it searchable by referencing variant forms of the author's name at indexing time. As always, all feedback is welcome! Best, Jörg -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Extremely interesting. Should be ideal for a fixed set of terms. I am still hoping for Matt Weber's pull request to be merged ( [Terms Lookup by Query/Filter (aka. Join Filter) by mattweber · Pull Request #3278 · elastic/elasticsearch · GitHub](https://github.com/elasticsearch/elasticsearch/pull/3278)) since I would like to denormalize against a dynamic set of terms, but your approach would be more efficient if handled at index time.
