Create text search queries

I'm unable to figure out how to create a graphql query for triggering basic mongodb fulltext search.

I have a single field in my mongoose schema as below.

const userSchema = new Schema({
name: String
....

and I have a text index on it.

userSchema.index({ name: 'text'});

And while I do see the index being constructed in my mongodb, I can't see anything in my graphql playground that would resolve to a $text query.

I was unable to find this in the documentation for graphql-compose-mongoose either. Maybe I'm missing something?
