 * Use this helper to project each record to include or exclude fields, returning a new record set of records with only those keys:
 * - String: `'a b -c +d'`.
 * - Array of strings: `['a', '-b']`.
 * - Object notation: `{ a: 1, b: 1 }` or `{ c: 0 }`.
 *
 * Inclusive if any field is positively specified (no `-` or `0`).
 *
 * Exclusive if only negatives (`-`) or zeros (`0`).
