SORT option not work

DEMO as follows：

(async () => {
  const si = require('../../')
  const cars = [
    {
      _id: 0,
      make: 'Volvo',
      colour: 'Black',
      year: 2011,
      price: 82580,
      model: 'XC90',
      drivetrain: 'Hybrid'
    },
    {
      _id: 1,
      make: 'Tesla',
      colour: 'White',
      year: 2012,
      price: 36693,
      model: 'S',
      drivetrain: 'Electric'
    },
    {
      _id: 2,
      make: 'Volvo',
      colour: 'Blue',
      year: 2005,
      price: 36130,
      model: 'XC60',
      drivetrain: 'Hybrid'
    },
    {
      _id: 3,
      make: 'Volvo',
      colour: 'Black',
      year: 2016,
      price: 42522,
      model: 'XC90',
      drivetrain: 'Diesel'
    },
    {
      _id: 4,
      make: 'Volvo',
      colour: 'Red',
      year: 2010,
      price: 60084,
      model: 'XC60',
      drivetrain: 'Petrol'
    },
    {
      _id: 5,
      make: 'BMW',
      colour: 'Black',
      year: 2013,
      price: 88503,
      model: '3-series',
      drivetrain: 'Diesel'
    },
    {
      _id: 6,
      make: 'Volvo',
      colour: 'Silver',
      year: 2011,
      price: 73297,
      model: 'XC60',
      drivetrain: 'Petrol'
    },
    {
      _id: 7,
      make: 'Volvo',
      colour: 'Silver',
      year: 2009,
      price: 55938,
      model: 'XC90',
      drivetrain: 'Petrol'
    },
    {
      _id: 8,
      make: 'Volvo',
      colour: 'Silver',
      year: 2010,
      price: 92375,
      model: 'XC60',
      drivetrain: 'Petrol'
    },
    {
      _id: 9,
      make: 'Tesla',
      colour: 'Red',
      year: 2008,
      price: 74017,
      model: 'X',
      drivetrain: 'Electric'
    },
    {
      _id: 10,
      make: 'Tesla',
      colour: 'Red',
      year: 2008,
      price: 74017,
      model: 'X',
      drivetrain: 'Diesel-2'
    }
  ]

  const print = txt => console.log(JSON.stringify(txt, null, 2))
  const db = await si({ name: 'QUERY' })

  await db.PUT(cars)

  console.log('\nSEARCH and SORT ->')
  await db.QUERY({
    SEARCH: ['make:Volvo', 'drivetrain:Petrol']
  }, {
    SORT: {
      TYPE: 'NUMERIC',
      DIRECTION: 'DESCENDING',
      FIELD: 'price',
    },
  }).then(print)
})()

When I did not pass in SORT, the result is as follows：

SEARCH and SORT ->
{
  "RESULT": [
    {
      "_id": "4",
      "_match": [
        "make:volvo#1.00",
        "drivetrain:petrol#1.00"
      ],
      "_score": 2.2
    },
    {
      "_id": "6",
      "_match": [
        "make:volvo#1.00",
        "drivetrain:petrol#1.00"
      ],
      "_score": 2.2
    },
    {
      "_id": "7",
      "_match": [
        "make:volvo#1.00",
        "drivetrain:petrol#1.00"
      ],
      "_score": 2.2
    },
    {
      "_id": "8",
      "_match": [
        "make:volvo#1.00",
        "drivetrain:petrol#1.00"
      ],
      "_score": 2.2
    }
  ],
  "RESULT_LENGTH": 4
}

But when I pass in, the result is still the same：

SEARCH and SORT ->
{
  "RESULT": [
    {
      "_id": "4",
      "_match": [
        "make:volvo#1.00",
        "drivetrain:petrol#1.00"
      ],
      "_score": 2.2
    },
    {
      "_id": "6",
      "_match": [
        "make:volvo#1.00",
        "drivetrain:petrol#1.00"
      ],
      "_score": 2.2
    },
    {
      "_id": "7",
      "_match": [
        "make:volvo#1.00",
        "drivetrain:petrol#1.00"
      ],
      "_score": 2.2
    },
    {
      "_id": "8",
      "_match": [
        "make:volvo#1.00",
        "drivetrain:petrol#1.00"
      ],
      "_score": 2.2
    }
  ],
  "RESULT_LENGTH": 4
}

I don’t know what to do. Please help.

@fergiemcdowall It seems the above API has changed and the docs are not updated. Reading the tests it seems you can now only sort based on what you specified in SCORE, is that correct?

[fergiemcdowall]

Yes- its not totally intuitive- this is probably something that could be explained better in the docs
