const queryObj = { ...req.query };
    const excludeFields = ['page', 'sort', 'limit', 'fields'];
    excludeFields.forEach((el) => delete queryObj[el]);

    //Advance filtering
    let queryStr = JSON.stringify(queryObj);
    console.log(queryStr);
    queryStr = queryStr.replace(/\b(gte|gt|lte|lt)\b/g, (match) => `$${match}`);
    console.log(JSON.parse(queryStr));
    //build a query
    const query = Tour.find(JSON.parse(queryStr));
