How to index a collection with strings in different languages?

Question

MongoDB

Let's say we have a User collection. It has a name field. One user has name: 'Vasya', and the second one has name: 'Vasya'.
I put the text index on the name field and mongo swears.
What can you think of?

The index is needed so that you can search for matches by characters
. You can, of course, use $regex for this to search for matches by characters, but I do not think that this will be fast in the long run.
