I have a need to use the output from the analyzer's in my index as an input to an external application. I could run the \_analyze function and collect/parse the token outputs but we'd like to restore that as a field in the index so that we can display them on Kibana visualizations and in Hive queries.

Can I create a field mapping that would dynamically be populated with the analyzer output on load?

Thanks 🙂
