Indexed DB - N-Dimensional Selection

The problem

We have an index with keys of the form:

[ dim1, dim2, dim3, ... ]

e.g. created with:

sebmarkbage

import { Component } from "React";

export var Enhance = ComposedComponent => class extends Component {
  constructor() {
    this.state = { data: null };
  }
  componentDidMount() {
    this.setState({ data: 'Hello' });
  }
  render() {

diffused

products = Product.select().where(
    Product.id << [161,162,163,164,165]).where(
        ~(Product.brand_name >> None)
    )
