Hello everyone, as the title suggests, I’m recently learning about mongodb and want to learn a bit about indexing; I have learned about ES before and know that ES uses inverted index, so I would like to ask if there is any information about inverted index in mongodb? And what are the performance implications of using an inverted index?
Thank you so much

Hi @Junguang_Wu, and welcome to the forums!
If you want general information about indexes, I strongly recommend this amazing course on MongoDB University on indexes. It covers a lot of information about indexes. If you prefer a quick read, you can check out this blog post on the topic.
When it comes to inverted indexes, they are used for full text search capabilities (ie: Atlas Search or ES). You can find more information about full text search on this blog post.
I hope this helps!
