Has anyone attempted to do lemmatization outside of elasticsearch on content, and fed the pre-analyzed tokens in document field and then ingested the document?

I would like to use spaCy lemmatization for content that I will be indexing into ES. I also would like to apply the same lemmatization on the query Text and then using that to query ES.

What kind of custom analyzer should I be setting up to achieve this?
