Mongoose text index on nested schema field

Question

I have the following schema:

const Schema = ({
  metadata: {
    title: String,
    ...
  },
  ...

});

and I'm looking to create aa text index on metadata.title . I can create a text index successfully on any first level property, but I'm running into trouble with the nested title.

I've tried the following code, to no avail. Is my syntax wrong? I've had no luck with docs...

Schema.index({ 'metadata.title': 'text' });

Searching:

Schema
  .find(
    { $text : { $search : req.params.query } },
    { score : { $meta: "textScore" } })

Answer 1

It turns out what I had originally was correct, as pointed out by @JohnnyHK. I must have had some other error that caused the index to not work...

Answer 2

 const Schema = ({ metadata: { title: { type: String, index: true } ... }, ... }); 

Answer 3

you may have to recreate the index with the new parameters or try to drop and recreate the collection
