mongo adapter - can't sort result with text search

[hawkins48b]

Prerequisites

• mongo db with index for textual search
• moleculer-db
• moleculer-db-adapter-mongo

Create a collection with basic data

broker.call('users.create', {
  username: "user01",
  name: "awesome user",
  zip: "54321"
}).then(res => console.log(res));

broker.call('users.create', {
  username: "user02",
  name: "awesome person",
  zip: "12345"
}).then(res => console.log(res));

Current Behavior

Perform a textual search with method 'find' or 'list'

broker.call('users.list', {
  search: "awesome",
  sort: 'zip'
}).then(res => console.log(res));

Does not sort results at all.

    username: "user01",
    name: "awesome user",
    zip: "54321"
  },
  {
    _id='cvWFC4MSWqFBxSYd4mwuBSVw',
    username: "user02",
    name: "awesome person",
    zip: "12345"
  }
]

Expected Behavior

We should be able to sort data with a text search.

As stated by the documentation, list should be able to perform a textual search and sort : https://moleculer.services/docs/0.13/moleculer-db.html#find https://moleculer.services/docs/0.13/moleculer-db.html#list

Again, I found out that the base adapter (memory) works. It is related to mongo. As a workaround, I use the 'find' method and sort results myself.

Steps to reproduce

Use the official example as a base : packages/moleculer-db-adapter-mongo/examples/search/index.js

• perform a textual search with method 'list' or 'find' and add parameter 'sort'.
• Results is not sorted.

Context

• moleculer 0.13.9
• moleculer-db 0.8.2
• moleculer-db-adapter-mongo 0.4.5
• moleculer-web 0.8.5
• NodeJS version: 10.3
• Operating System: Alpine Linux (run in a docker container on Ubuntu 18.04)
