Tokenizer for Search Index that works as split_on_case_change elastic search parameter

Hello

We need to re-create our search index because we’ve figured out that there are a lot of data filled using camel case pattern. We were using the find operator before (which was terrible slow) that was replaced by the Atlas Search. But, the first way returned the searched term, but without splitting on case change, Atlas Search does not.

I’d like to know if there is a single flag or similar that could be used. If no, some RegEx pattern which is recommended, cause I’ve found dozens of them, with several related issues.

Thanks for now
