Atlas Search regex - how to specify case insensitive?

Not clear how to do. https://docs.atlas.mongodb.com/reference/atlas-search/regex/

Hi @Fred_Kufner,

I suggest to read the following README developed by one of our engineers regarding atlas search case insensitive queries:
https://github.com/MarcusSorealheis/Flask_Tuts/tree/fts_version#the-common-regex-anti-pattern

I think by design many analyzers are case agnostic and if you.cant achieve it look for a custom lowercase tokenizer
