Generating extra-fields to my results based on query

Hello @amrmostafazaki

Thanks for your response.

Indeed I'm pretty sure it's all about that, you're right, but do you know if I can do that with a Query ?
To be clear, can I run a "match_phrase" with fuzzy for typos, levenstein distance... instead of a "IndexOf" like this ?

Thanks again
