How to organize case insensitive search in mongoDB?

Question

MongoDB

Hello! I have a collection, which consists of about 200 entries (in the future this number will constantly grow). I need to organize a case-insensitive search on the field name and descr .
I read about full-text search, but it is now working in test mode (and it is case-sensitive, despite the fact that the documentation says otherwise).
Please tell me how to quickly organize the search (I think it will be too dreary to install a search engine [the project is not big]).
PS: I am using mongoose and node.js
