Mongoose: Can't set multiple text indexes in schema

[dertieran]

I want to make the title and the description field search-able.
I'm using node.js 6.9.1, mongoldb 3.2.11 and mongoose 4.7.1.

Schema:

const Schema = new mongoose.Schema({
    ...
    title: { type: String, required: true, text: true },
    description: { type: String, text: true }
    ...
})

But when I connect to the database just the title field is added as a text index.

$ mongo
MongoDB shell version: 3.2.11
connecting to: test
> db.podcasts.getIndexes()
    ...
    {
        "v" : 1,
        "key" : {
            "_fts" : "text",
            "_ftsx" : 1
        },
        "name" : "title_text",
        "ns" : "test.podcasts",
        "background" : true,
        "weights" : {
            "title" : 1
        },
        "default_language" : "english",
        "language_override" : "language",
        "textIndexVersion" : 3
    }
    ...

Using schema.index() works as expected

const Schema = new mongoose.Schema({
    ...
    title: { type: String, required: true },
    description: { type: String }
    ...
})

Schema.index({ title: 'text', description : 'text' })

$ mongo
MongoDB shell version: 3.2.11
connecting to: test
> db.podcasts.getIndexes()
    ...
    {
        "v" : 1,
        "key" : {
            "_fts" : "text",
            "_ftsx" : 1
        },
        "name" : "title_text_description_text",
        "ns" : "test.podcasts",
        "background" : true,
        "weights" : {
            "description" : 1,
            "title" : 1
        },
        "default_language" : "english",
        "language_override" : "language",
        "textIndexVersion" : 3
    }
    ...

Schema.index() is the preferred way to create a text index, using text: true in individual fields is not recommended because text: true on multiple fields will attempt to create multiple text indexes, which doesn't work in mongodb.
