Thanks so much for your contribution @ScottieL. I left a few comments for needed changes. Let me know if you have any questions.

Thanks for the changes! I figured I added a little much but wanted to be thorough.

Hi @ScottieL

Before moving forward, can you address this comment:
https://github.com/elastic/elasticsearch/pull/48011/files#r334672652

I think it may be helpful to link to the stopwords list in Lucene where applicable. I included an example for Arabic below.

Those changes are pretty substantive, but I believe they're important to users. The current links require a bit more work to find the actual stopwords.

This PR is almost ready for merge. I left some additional suggestions.

I feel I led you astray with my example link. While the files are identical in most cases, we should link to the Lucene source files rather than the Solr example files where possible. My example was the latter. My apologies for the mistake.

Thanks again for your work on this PR.
