A flexible, lightweight MongoDB query utility for Node.js applications. Simplifies database operations with intuitive filtering, pagination, sorting, and field selection. Ideal for REST API endpoints, providing a primary List class that abstracts complex

   v = Number(v)
   if (isNaN(v) || (min !== undefined && v < min) || (max !== undefined && v > max)) return

   if (!search[key]) search[key] = {};
   search[key][subKey] = v
};
